[FIX # 2184] Add clip, clip-path check; Add parent visibility check

[Felix026x]

To solve Issue #2184, we modify the original method for visibility check, and consider the hidden techniques using clip and clip-path. We also fix the style issue, where the original code utilizes the style of the inline element while overlooking the nested CSS styles. However, for performance overhead, we do not implement the detection for hidden fields caused by overlays.

Are there any common known sites that are affected by this change and can be used for testing?

This fix does not work for me. I tested this with the first URL in the issue (https://felix026x.github.io/overlay.html) and after filling (with this change or without) document.querySelector('#password')?.value still returned the filled password.

Thanks for your comments. As we describe in the first thread, we do not consider the overlay cases for performance consideration. However, cases like clip and clip-path should work well.
