When RenderQuote updates text, it blows away all the existing children. In case of :first-letter, it destroys the first letter and then the remaining text fragment. This cause the remaining text fragment to retain stale pointer to first letter and crash. We just reverse the destruction order to prevent this from happening.

Update missing lines to match the bots post content shell transition.

There are now only 5 flaky Missing lines now and they don't seem to
be Mac specific anymore. At least a couple of these look like they
may be genuine web-exposed bugs.

The different drawing pipeline on windows content shell produces slightly different pixel results due to differences in the fixed point arithmetic implementation, but are otherwise correct.

Use HTMLElementFactory to create equivalent elements in WebVTTElement.

This change forces the calls through the factory so that we create
appropriate sub-classes based upon the passed tag name, rather than
just creating a concrete HTMLElement class with an inappropriate tag
name.
