testcase

Steps to reproduce:
 1. Open the attached testcase.
 2. Click the button twice.

Expected results:
The initial state of the page should appear the same as the state after clicking the button twice.

Actual results:
The second click on the button turns the element with the backdrop filter white. On page load it was gray.

I don't actually know what the correct behavior here is, but it should at least be consistent.
