GIF showing filter enabling and disabling. Text changes, bg does not
EXPECTED: `body { filter: grayscale(100%); background: green; }` will show a gray background on a web page.
ACTUAL: Background remains green.
This is preventing successful run of my grayscale bookmarklet (<a href="https://alanhogan.com/bookmarklets#grayscale">https://alanhogan.com/bookmarklets#grayscale</a>) from running successfully.
