> What would you suggest?
1- Don't use invisible text, remove the text instead.
2- Start any command where it can matter with a call to a function that
skips forward over invisible text.
3- Make your invisible text intangible (ideally with cursor-intangible,
since the `intangible' text property has all kinds of nasty side
effects), so the cursor can't stay inside.
4- Some other solution of your choosing.
> What would a different case that is not a bug in Emacs look like?
Hmm... I did give you examples:
if the command that moves point started/ended in another buffer, or
if the command set disable-point-adjustment, plus a few other cases.

Why not?

Magit is the one which introduces invisible text.
The core functions can't know exactly why the text is invisible and
hence what to do about it in each and every possible case. Only Magit
knows that.
