When you say "disappear", do you mean "deleted from the file system"
or something else?

It's not in branchA, it's just no longer ignored because your changes
to .gitignore were effectively reverted by jumping back to the commit
that branchA points to.

"hide/reappear" is the equivalent to saying "deleted/created" in the
case of a tracked file in your working tree.  But how would Git cause
an untracked file to reappear?  By definition, it doesn't know
anything about the file.

I posted an answer there, too, but I'm not sure I fully understand the
problem.  The top-voted answer doesn't make much sense, though.
