1687873 - /css/css-ui/resize-child-will-change-transform.html fails with the non-native theme enabled

Status: RESOLVED DUPLICATE of bug 1689253

(Core :: Widget, defect, P3)

Description

[Cameron McCormack (:heycam)]

The test fails as the <textarea> resizer has a different size in the test than it does in the reference. For the one with scrollbars, the resizer ends up at 12px, matching the scrollbar width. For the one without scrollbars, the resizer ends up at 15px, the default size as set in https://searchfox.org/mozilla-central/rev/2c06b16a0c15ae340a0532e319cbf89ef9d21b68/layout/generic/nsGfxScrollFrame.cpp#6793-6795.

(The way the <resizer> always matches the scrollbar width doesn't really work with scrollbar-width: thin, where it just looks too tiny, but that's a pre-existing problem.)

We should maybe adjust the default 15px to instead use some LookAndFeel value that provides a default that matches the theme's normal scrollbar width.
