The final SPC after the closing equal sign lets point jump to before the
colon of the ":test:" tag.
Most likely, this is not limited to space, but that is just the
character I most frequently type after closing emphasis.

Confirmed.

No, it is space. In particular, it is `org--align-tags-here' + some bug
in Emacs that screws up column computation.

Well, I have one not-so-minor nit here: With that commit you cannot
insert text *before* some text having hidden emphasis without breaking
the emphasis. More concretely (in an empty org-mode buffer):
t ;; org-self-insert-command
e ;; org-self-insert-command
s ;; org-self-insert-command
t ;; org-self-insert-command
SPC ;; org-self-insert-command
= ;; org-self-insert-command
t ;; org-self-insert-command
e ;; org-self-insert-command
s ;; org-self-insert-command

= ;; org-self-insert-command
SPC ;; org-self-insert-command
t ;; org-self-insert-command
e ;; org-self-insert-command
s ;; org-self-insert-command
t ;; org-self-insert-command
C-<left> ;; left-word
C-<left> ;; left-word
SPC ;; org-self-insert-command
The last SPC breaks the emphasis around the middle "test", which it did
not previously. Previously, the SPC would just move the whole
emphasized word one space to the right. Which I somehow got used to,
and probably many others as well.
OTOH, to fix my bug, only the first of the new `org-rear-nonsticky-at'
calls is actually needed. So probably we could have something like the
following to get my bug fixed without any changes in behavior (diff on
top of main, that is, in addition to your commit):

OMG. What we had in the past is because of an obscure internal,
undocumented implementation detail of how Emacs adjusts point when it
ends up inside invisible region:
/* If the preceding character is both intangible and invisible,
and the invisible property is `rear-sticky', perturb it so
that the search starts one character earlier -- this ensures
that point can never move to the end of an invisible/
intangible/rear-sticky region. */
Except that we do not have intanglible property there and the code below
that comment does not always check for intanglible property.

I am not sure if it is a proper fix. The basic problem is that Org's
syntax table does not declare emphasis markup as part of a word.
I need to consult Emacs devs about rules of point adjustment.

The root cause revealed by my change is that Org mode does not always
consider emphasis markers to be word boundaries.
Note how when you do not hide emphasis markers, C-<left> will end up in
*<point>foo*
When emphasis markers are not hidden, things were the same, except that
Emacs adjusted point right to sticky invisible text in the direction of
point movement, leading to inconsistent behaviour between hiding and not
hiding emphasis markers.
Yet, Org sometimes does treat emphasis markers as word constituents:
At least, `org-fill-element' and `org-transpose-words' temporarily turn
emphasis markers into parts of words.
The situation is clearly a bit chaotic.
One of the reasons why we have such a mess is because *_/~+ are not
always representing emphasis. Proper distinction between *_/~+ that are
and aren't part of actual emphasis would require a custom
`syntax-propertize-function' that would query Org element API to
determine the context.
Unfortunately, using `syntax-propertize-function' it is not very
practical yet.
We need parser context down to object level, while we only cache parser
state down to element (paragraph) level. So, querying element API in
this case will lead to significant performance degradation, with
quadratic (N_objects_in_paragraph^2) complexity in some cases.
I will leave this bug report open until we have a better caching and can
reasonably implement custom `syntax-propertize-function'.
Or, if any, please post arguments against making emphasis markers word
constituents.

I see no good way to address this quickly, so I re-added stickiness to
the opening emphasis marker, as you suggested.

FWIW the third test yields
■ Warning (emacs): Test #3:: ’word’ is hidden applying ’invisible
text property to heading body.
■ Warning (emacs): Moved point after first ’word’
■ Warning (emacs): 1:: current-column = 0
■ Warning (emacs): redisplayed
■ Warning (emacs): 2:: current-column = 0
■ Warning (emacs): Indented to column 50

And for the fun of it: With (indent-tabs-mode -1) tests 3 and 4 report

I think it is same.

Interesting.
Same for me.
I will update the bug report.
