  [IFC][initial letter] Intrusive initial letter introduces clearance
https://bugs.webkit.org/show_bug.cgi?id=250278

Reviewed by Antti Koivisto.

See the comment in LineBuilder::adjustGeometryForInitialLetterIfNeeded.
(When we need to clear an intrusive initial letter (to place the current line's 
initial letter)
the line "moves" after the clear position introducing a "before" clearance.
This ensures that containing block's logical height is correct by taking this 
clearance into account.
