Bugzilla

Since this bug is trying to "force scrollbars flag to be always enabled for new window", I remove all places of "set scroballbars flag" from our tests in the latest revision. 

Only two of them will affect the result:
dom/html/test/test_bug369370.html: Fix the failure by refining the test.
layout/base/tests/test_transformed_scrolling_repaints_3.html: The scrollbar will affect the result on windows. After investigation, we can enlarge the new window to prevent the scrollbar and it won't affect the test purpose and result.

However, if we want to keep the ability to disable scrollbars, maybe we should enable a preference for testing. What do you think?
