Thanks for testing!

The problem here is that emphasis markers and links are also partially
hidden and it is a good idea to check invisible edits there.
It's just that they were ignored by org-catch-invisible-edits in the
past. But not anymore.

I afraid that it is impossible to follow the present docstring for
org-catch-invisible-edits without mixing 'error/'show-and-error with
'smart. It's perfectly fine to insert text right after trailing ]] of
the links, but, as you showed, not after folded headline contents.

Now, we have different kinds of hidden text at hand:
- folded headlines/lists
- folded drawers
- folded blocks
- folded links/emphasis

The question is what should be the logical behaviour of Org when editing
text inside or at the border of these hidden text types? How should we
interpret the values of org-catch-invisible-edits (nil error show
show-and-error smart)?

Best,
Ihor
