<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/191195">r191195</a> - First line box in paragraph using initial-letter overflows.
https://bugs.webkit.org/show_bug.cgi?id=147977
<rdar://problem/22901553>
Reviewed by David Hyatt.
When initial-letter float is present, we should shrink the first
line even if it's not intersected with the block's current height.
This is because of the sunken behaviour of initial-letter.
