Perspective Popup zIndex

I am having issues from time to time, where a popup goes behind another popup in perspective.
Can i use zIndex or can i request focus for popup in perspective.

Perspective Popup z-index is based on which was most-recently provided focus.
If Popup A is open and you open Popup B, Popup B receives focus on open, so it’ll be on “top”. If you then click Popup A, focus moves from B to A, so now Popup A will be on top. There is now way to request focus for a popup, although you could hijack the focus by closing and immediately re-opening the Popup in question.

# This would close 'PopupA' and then immediately re-open it, providing the illusion of focus.
system.perspective.closePopup(id='PopupA')
system.perspective.openPopup(id='PopupA')

It kind of works if my popup window PopupA isn’t open it closes the other popup.
if it isn’t open it closes all open popups.
Not what i wanted.

Ah, that’s a side-effect of a bug that was fixed in 8.0.13. I forgot that could be an issue prior to that (upcoming at this point) release. Prior to 8.0.13, there is no way to mimic focusing a popup.
