Realized on reading that as posted that it implies the browser folks had 
to change their behavior regarding raising the password dialog.  That 
wasn't intended and (AFAIK) isn't necessarily accurate (I unintentionally 
made a statement I can't initially verify one way or the other).

What I /intended/ to say was that in my chosen example, they had to change 
both password dialogs and their general web-page-popup behavior, primarily 
web-page-popup appearance, to ensure that web-page-popups were distinct 
enough from system dialogs (password and other, browser and not) that 
there was no confusion, and that while raising and focus behavior may in 
the abstract be different from that, be careful that any changes to focus 
behavior rules you make, don't inadvertently neutralize behavior they may 
have instituted due to security concerns that might be unrelated to the 
particular example I named.

IOW, just be aware that a browser is arguably the most security exposed 
sensitive app most people commonly run, and that any changes you make to 
its default behavior, including apparently security-unrelated changes, may 
have unintended consequences in terms of its security posture.  With that 
awareness and assuming a reasonable security sense that unfortunately many 
folks don't seem to have (but just the fact that someone's posting/reading 
here suggests a higher likelihood they do, due to self-selection meaning 
the least security-aware wouldn't be here in the first place), proceeding 
cautiously should be reasonable, but be particularly alert for unusual or 
unexpected behavior for awhile after that, just in case.
