  [IFC][hanging punctuation] Non-whitespace hanging content contributes to scrollable overflow
https://bugs.webkit.org/show_bug.cgi?id=249857

Reviewed by Antti Koivisto.

"An overflowing hanging glyph should typically be considered ink overflow so as to avoid creating
unnecessary scrollbars, but the UA may treat it as scrollable overflow when the content is editable
or in other circumstances where treating it as scrollable overflow would be useful to the user"
