1939891 - Allow remaining hard-coded XUL frames (like <xul:image>) to be out of flow.

Status: RESOLVED FIXED

(Core :: Layout, defect)

Description

I was confused as for why bug 1933479 couldn't position the icon using absolute positioning or what not. It's just because of legacy reasons.

Just like their HTML counterparts. The only reason they couldn't in the
past was because they were using XUL layout, but that is long gone and
now things like <browser> use nsSubDocumentFrame, <image> uses
nsImageFrame etc. Relevant HTML counter-parts like <img> do support
this.

Let me know if you want to add a test for this, but it's just removing
legacy special cases so I'd rather avoid it if I can :)

Can we back this out of beta for causing bug 1940698?
