606606 - Text inside <panel type="arrow"/> isn't wrapped

Status: RESOLVED INVALID

(Core :: XUL, defect)

Description

[Mounir Lamouri (:mounir)]

With regular <panel/>, if a textNode is set (directly on the panel or inside a  <description/>) in addition of a max-width property, the text is wrapped.
If you change <panel/> to <panel type="arrow"/>, the text isn't wrapped anymore.

On Linux, given that the arrow isn't shown, max-width is working but not the wrapping. On MacOS and Windows, because of the arrow, max-width is even ignored.

You can test that with "invalid-form-popup" panel in browser.xul.

This is fixing the issue on GNU/Linux. I have to check on a platform supporting the arrow if there are no side effects.

So there are no side effects but this is not fixing the issue on Mac :(

It is but when converting from <panel/> to <panel type='arrow'/> we are loosing orient="vertical" and we need to set the max-width on the <description/> inside the panel instead of the panel itself.

It was confusing for a non-XUL dev like me :)
