<h3>Log Message</h3>
<pre>Dragging text from one paragraph to another does not render as expected
https://bugs.webkit.org/show_bug.cgi?id=132633

Reviewed by Darin Adler and Ryosuke Niwa.

Source/WebCore:
When we are dragging and dropping into a content editable field, we detect
if we are trying to put a &lt;p&gt; into an existing &lt;p&gt;, and if so, split the
outer &lt;p&gt; and insert the new &lt;p&gt; as its sibling. However, the outer &lt;p&gt;
might not be editable, so we don't want to do any splitting and inserting
at that location.

Test: editing/pasteboard/drag-drop-paragraph-crasher.html

* editing/ReplaceSelectionCommand.cpp:
(WebCore::ReplaceSelectionCommand::makeInsertedContentRoundTrippableWithHTMLTreeBuilder):

LayoutTests:
The problem occurs when dragging text that includes a &lt;p&gt; into an editable
area that has a &lt;p&gt; as a parent.

* editing/pasteboard/drag-drop-paragraph-crasher-expected.txt: Added.
* editing/pasteboard/drag-drop-paragraph-crasher.html: Added.</pre>
