That's on purpose.  Of course, it's not always the right choice, but
imenu is supposed to let you go to the "definition" of something and
this is not a definition.

Yes, that's a false positive.  It's difficult/impossible to avoid all
false positives and all false negatives.  We could try and recognize
this particular case with ad-hoc code, but it wouldn't help in general.

Agreed.
