Some history:

- 289777@main (fix for bug 286995) was when the original quirk landed, which correctly applied the animations but had a slight flash at the beginning.

- 300237@main (fix for bug 298838) by Sam Weinig was when the flash was removed and hotels.com was in the best state in Safari, matching Chrome’s behavior.

- 302416@main (fix for bug 301581) also by Sam Weinig was when things regressed to the current state :(

Perhaps the code added in 289777@main was no longer optimal with how the style system works with animations anymore, or perhaps it's actually a bad regression we must fix. I think we need to understand what’s wrong with the original Quirks code before making a change and engage with Sam Weinig, the author of 302416@main, to get to the bottom of this. I've Cc'd him to this bug and left a comment on bug 301581.

2. Navigate to hotels.com
3. In the top left corner of the website, tap “shop travel”

Results:
It should not flicker. It does flicker again.
