Backdrop Filter should not be visible if element has visibility:hidden.
* STEPS TO REPRODUCE
1. Open test
=> did not expect div with visibility:hidden to still have blur visible
Just wanted to add that if the parent element has visibility:hidden, the child that has the blur will still composit the blur onto the page, even though it is expected that all content within the parent, including the child would be hidden.
