blog.rekhta.org: Text underline does not work properly for Urdu Text
https://bugs.webkit.org/show_bug.cgi?id=321816

Reviewed by Brent Fulgham.
WebKit's underline ink-skip painting exempts CJK-family scripts from per-glyph
ink
detection. Arabic-family connected scripts like Urdu Nastaliq hit the same
problem: a
single glyph's ink envelope can span nearly its full width, so skip-ink treats
most of
the underline as intersecting ink and paints only a few disconnected segments.
This
extends the CJK exception to the Arabic-family Unicode blocks.
