Add optional annotations for initEvent method of Event interface
Added `optional` and default values to parameters `bubbles` and `cancelable` of `initEvent` of `Event`.
I tried to update test results, but there seem to be no differences at all.
I checked similar code where `optional` is used, and there seems to be no special handling in Rust. If that is not the case with this issue, please let me know and I'll commit more follow-ups.

Ensure transparent hit test region is sized and positioned correctly.
This addresses some edge cases that were missed by #22156. Specifically, in some cases the transparent region was being placed in the display list in front of the scrollable content, rather than behind it, and the size of the region did not account for parent stacking context.
