Replaced elements squeezed when width is specified as percentage inside a table with Auto layout
https://bugs.webkit.org/show_bug.cgi?id=29447

Source/WebCore:

If inserting a 'replaced' element (e.g. image, plugin) in a table cell that is not descendant from
a block with fixed layout then do not squeeze the element, let it use its intrinsic width and height.
