We should probably merge
https://chromium.googlesource.com/chromium/blink/+/628ec64c197dc92c5e87b1c4f7b6e13af1f86b75
Since rules in scoped styles could be treated as scoped selector rules, we don't need to full style recalc.
So updated in the following way:
- register with scoping node before invoking DocumentStyleSheets::updateActiveStyleSheets.
- move needsStyleRecalc logic for scoped styles from HTMLStyleElement to StyleInvalidationAnalysis.
- make StyleInvalidationAnalysis support scoped styles.

This one caused assertion failures.
https://chromium.googlesource.com/chromium/blink/+/f253680301e93041b6ba02d95a31ca931e7a8f9e is what we want.
