Unexpected word wrapping for wrapped content then raw content.
https://bugs.webkit.org/show_bug.cgi?id=121130
Reviewed by Darin Adler.
When deciding whether a line is considered empty, we need to check if the current
object is fully responsible for the currently uncommitted width. It helps differentiating
<span></span><span>abcd</span> from <span>a</span><span>bcd</span>, where in the first
case when we hit the second <span> the line is still considered empty, as opposed to the
second example.
This patch introduces a map to keep track of the uncommitted widths.
