Avoid stalled pages containing unreachable stylesheets
This hits some of the pages in the performance testsuite, and leads to a poor user experience since the document load event is never dispatched and the page never finishes parsing.

Text fragment color merge
The display list item for a line of text has a single color assigned for
it, so text fragments with different colors cannot be merged.
There is no issue number for this, as far as I know. I found this while
trying an internal program that uses red asterisks for required text
fields.

gfx: Don't create paint threads when WebRender is in use.
They're unused and just waste memory and process table entries.

There's a bit of flickering when unpausing where the node has the original
state, but I'm not totally sure where it comes from, posibly from
PropertyAnimation returning None due to no styles changing?
