1354975 - stylo: Calling nsIFrame::AttributeChanged() in ServoRestyleManager::AttributeChanged()

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, enhancement)

Description

[Ting-Yu Lin [:TYLin] (PDT, UTC-7)]

GeckoRestyleManager::AttributeChanged() calls nsIFrame::AttributeChanged() in [1], but ServoRestyleManager doesn't do the same.  By doing so, we can fix some tests in stylo [2].

This also help fixes the scrollbar (bug 1321769) because nsSliderFrame::AttributeChanged() need to do some work.

Nice find!  I see that GeckoRestyleManager::AttributeChanged also does some checking for themed widget stuff, just before where it calls nsIFrame::AttributeChanged.  We probably need to do that -- can you file a bug for that?
