Log Message:
-----------
[HTML-in-Canvas] drawElementImage() should invalidate the canvas
https://bugs.webkit.org/show_bug.cgi?id=327282
rdar://189835414
Reviewed by Said Abou-Hallawa.
drawElementImage() draws the element's snapshot into the canvas without
reporting the area it changed, so the canvas is not invalidated and keeps
showing its previous contents until something else draws into it.
In this PR we report the destination area before drawing.
