test

Noticed this looking at https://developer.apple.com/documentation/coretext/1510813-ctfontgetglyphsforcharacters?language=objc.

STR:

1. Open the attached test.
2. Click somewhere in the "Char" of "UniChar".
3. Notice that the line of text wraps (and not all of it gets repainted).

Are we incorrectly computing the intrinsic minimum width of the text by not taking into account the word wrap opportunities?

Doesn't reproduce with LFC for inline layout turned off.
