Do you mean that the cursor is moved from whatever
position it had to the beginning of the file name
of that _same line_?

Or do you mean that the cursor is moved from
wherever it was to a different line (at the
file-name beginning)?

If you mean the former (above), then this is the
standard movement location: beginning of file name.
It's what you get when you use `n' or `p', for
example.  The current line is recorded as part of
a Dired buffer's state.  The cursor position is not.

I can't speak authoritatively to the new vanilla
Dired breadcrumbs behavior about this.  But if you
use Dired+ then what I describe above happens: the
cursor is placed on the same line, at the file-name
beginning.

A breadcrumbs difference wrt between vanilla Dired
and Dired+, I believe, is that the vanilla behavior
is that function `dired-revert' is always used,
instead of whatever function is currently the value
of `revert-buffer-function'.

For example, with Dired+ in a `find' Dired buffer,
clicking what you call the "base" name (the last
component of the absolute file name) runs the `find'
command again, to refresh its listing.

With vanilla Dired, I believe that even in a `find'
Dired buffer clicking there just lists the default
directory.  I think using the `revert-buffer' of
the given buffer is more useful (e.g., in the case
of `find', redo the `find').  There are lots of
buffer modes that derive from `dired-mode', and
they sometimes have different revert functions.
To me, it makes sense for reverting them to use the
function defined for the specific mode.
