591186 - noautohide panels moving vertically when parent window is resized

Status: NEW

(Core :: XUL, defect)

Description

[Daniel Glazman (:glazou) (not active in Mozilla any more)]

I started using <panel noautohide="true" level="parent"> in BlueGriffon and hit a curious bug on Mac OS X (Snow Leopard). If I resize the parent window, the floating panel is moved vertically even if the popupnode's position is not at all changed by the window resize.

I did a video capture of the bug available here:

How are you opening the panel here? What is it anchored to?

openPopup(). Anchor element is document.documentElement.

2.5 years after reporting, this bug is still here and plagues BlueGriffon's panels.

Looks to be the same bug as 682732, which has some analysis I did some time ago in it.
