Description Chris Dumez 2023-06-14 08:59:30 PDT 
HTMLFieldsetElement behavior for :enabled / :disabled CSS selectors is incorrect since 264098@main (when sendMouseEventsToDisabledFormControlsEnabled experimental flag is enabled).
This is because it updated HTMLFieldSetElement::isDisabledFormControl() to return false. However, the CSS selector should rely on the "actually disabled" state, not the "disabled" state.
