third_party/WebKit/LayoutTests/NeverFixTests

 # This file should only include tests that we never intend to fix.
 # There should only be 4 categories of tests here:
 #   1. Test harness tests.
 #   2. Tests enabled by chromium embedders (e.g. Opera).
 #   3. Tests that apply to some platforms but not others.
 #   4. Tests that are too slow in Debug and so we only want to skip them in Debug.
 
 # FIXME: Remove the WontFix keyword and have that be implied. That way, people won't abuse
 # WontFix outside of this file.
