Re: [fxtf-drafts] [filter-effects] SVG filter for invert not working properly (#462)

> That wording was [added in 2017](https://github.com/w3c/fxtf-drafts/commit/1e2a527ca8e69bbbbd7f6a5e80bd08eac01529b5).

In my defense, that test compares `backdrop-filter` to `filter` to make sure they do the same thing. Using other filter functions such as `blur` for that causes flakiness due to sub-pixel stuff.
