No space!

Shouldn't have a space here either.

Aren’t isolated runs needed for supporting explicit directional isolates (LRI, RLI and FSI)? See <http://www.unicode.org/reports/tr9/#Explicit_Directional_Isolates>.

Mitz: Yep, but we don't honor those currently. I filed a bug about it recently: https://bugs.webkit.org/show_bug.cgi?id=149170

At least, I should say that our isolate infrastructure requires isolates to come from RenderElements. (Maybe we generate RenderElements for these codepoints and I've just not seen where we do that).

See constructBidiRunsForSegment().
