Is this change fine for stable as well? (If not, you could always update the Flutter SDK requirement so Flutter 2.2 won't versions that have this change.)

Yes, thanks for asking. I tested this both with stable and master, manually and with the driver tests.

This is backwards compatible, it's just that there's many ways to "cover a parent div" with CSS, but in the engine we only check "are style.width and style.height set (to any value?) else: warn user".

This code is to disable that warning from our own packages.

if (debug) {
htmlElement.style.backgroundColor = 'rgba(255, 0, 0, .5)';
}
