-----------
[text shaping] Shaped content may break at arbitrary position causing
incorrect resolved width
https://bugs.webkit.org/show_bug.cgi?id=299226
Reviewed by Antti Koivisto.
Let's reshape line candidate content when we need to break it up at arbitrary
position.
1. Find shaping boundary end after trailing run (if there's one)
2. Walk back from trailing run to find boundary start.
3. Reshape from start until the last text content (trailing run may be inline
box)
(in some cases the trailing content is the shaping start in which case we don't
have to shape it anymore -at least not in the sense of across boxes)
