Maybe say something about the other changes in this patch.

What about negative X?
Don't you also need to check the element width? Something at -999 could be on-screen, especially if it has 100% width on iPad.
You should also add a test for this.

I did, it's next to "StyleChangeScope::isConsideredHidden const" but yeah, I should put some more words in there.

That case is covered already. This is about when we don't know the exact width (percent or calculated) and the _out-of-flow_ content seems suspiciously positioned to the far left.
