Cleanup inline boxes when list marker gets blockified
https://bugs.webkit.org/show_bug.cgi?id=195746
<rdar://problem/48049175>
Reviewed by Antti Koivisto.
Source/WebCore:
Normally when an element gets blockified (inline -> block) we destroy its renderer and construct a new one (RenderInline -> RenderBlock).
During this process the associated inline boxtree gets destroyed as well. Since RenderListMarker is just a generic RenderBox, the blockifying
change does not require a new renderer.
This patch takes care of destroying the inline boxtree when the marker gains block display type.
