  [IFC] Trailing inline box width should include hanging content
https://bugs.webkit.org/show_bug.cgi?id=266945

Reviewed by Antti Koivisto.

Let's include trailing hanging content when computing the logical width of the parent (non-root)inline box.
e.g.
<div style="white-space: pre-wrap">this line end in a hanging whitespace<span>
</span>some more text</div>

- merge isInlineBoxStart and isLineSpanningInlineBoxStart handling
- add initialLogicalWidth lambda and take hanging content width into account
- move more common content (text, line break) handling to the top of this loop
