1707557 - fix TransformFrameRectToAncestor call in DoubleTapToZoom for fixed content where the ancestor frame isn't an ancestor

Status: RESOLVED FIXED

(Core :: Panning and Zooming, defect)

Description

[Timothy Nikkel (:tnikkel)]

Attachment: fgs4.html

Bug 1705599 made the calculation we do in nsLayoutUtils::GetBoundingFrameRect work if its inside fixed content. But bug 1701749 added a similar calculation in DoubleTapToZoom.cpp which we didn't fix up for the same problem.
