What happened?

The page is stuck loading for quite a while. Recording a trace shows that it's related to StyleEngine calls.

What did you expect?

The page should load with a similar speed to visiting it normally in Chrome.

What have you tried?

I tried bypassing any CSS.enable calls, and the page loads as expected.

Not sure if this is still related to this issue? #15890

I can reproduce this. #15890 this issue was related to CSS rule usage tracking but perhaps we should try to prevent the entire CSS domain from being enabled during a run.

This will be more challenging than #15890 though because enabling the CSS domain is the only way to track transient style sheets.

I have no idea what you are talking about. This is driving me crazy. I do not mean to ignore your emails. Thank you for contacting me but I need to speak with someone directly to help me figure this out.
