If there's ::first-letter pseudo element on the multicol container,
ColumnSetWrapperFrame will have the first letter style, but it won't get
the NS_BLOCK_HAS_FIRST_LETTER_STYLE bit during frame construction. The
actual first-letter frame construction happens under -moz-column-content
anonymous block.
This patch excludes ColumnSetWrapperFrame from the debug check to meet
the expectation.
Add a reftest to make sure ::first-letter and ::first-line still work
after introducing ColumnSetWrapperFrame, and no assertion is fired.
