Hover Text not displaying with multiple windows

[CraterLabs]

Incredibly low-stakes issue, but I've noticed this for ages and never seen it talked about so...

 

If you have multiple windows open (such as the badge tab, the recipe inventory screen, and the auction house window), then hovering your mouse over some things that usually give you pop-up text (such as the text telling you the specific numbers for how far along a badge's progress bar you are) won't make the text pop up.

 

My guess is that it's because the pop-up text probably counts as its own window somehow, and having three other windows open interferes with having the text show up, but I've never looked at the code so my idle musing is effectively useless.

For example: here's a screenshot of the text usually popping up, and one where it, uh, doesn't

 

 

Two windows open in one, three in the other.

 

Again, this isn't really an "issue", though it is sometimes an annoyance if I go to Wentworth's with a portable crafting table, heh.
