What are all these scrollbar settings diffs?

[Xianzhu, 2015/10/29 04:22:01]

This is to let the tests paint scrollbars using the mock theme instead of the
native theme.

The native theme is implemented at chromium side. It requires some resources
that are not initialized or not available for webkit tests and will crash.

Before sync painting, the tests didn't trigger paint and the problem.

I see. You should tell schenney@ about that since he is investigating getting
rid of the mock theme, but it seems this is a reason to keep it.
