Re: [fxtf-drafts] [filter-effects-2] Backdrop filter clipping with edgeMode="duplicate" creates discontinuity when moving. (#374)

The CSS Working Group just discussed `[filter-effects-2] Backdrop filter clipping with edgeMode="duplicate" creates discontinuity when moving.`, and agreed to the following:

* `RESOLVED: change backdrop-filter's edgeMode to mirror, pending any objections`

<details><summary>The full IRC log of that discussion</summary>
&lt;TabAtkins> flackr: So edgeMode=duplicate we specced creates a flickering discontinuity<br>
&lt;TabAtkins> flackr: I propose we change the edgeMode for backdrop-filter to be reflect<br>
&lt;TabAtkins> flackr: Which smoothly introduces new colors as they enter the edge. It's *probably* what Safari is doing but I"m not sure, they haven't commented.<br>
&lt;TabAtkins> flackr: I wanted this resolved before Interop 24 tries to standardize this beahvior<br>
&lt;TabAtkins> TabAtkins: I haven't looked at the details but I hate flickering, and trust flackr to have the right option for making it look good<br>
&lt;TabAtkins> fantasai: I think think we have someone working on backdrop-filter issues and they're out right now. I have confidence in flackr but I"d like to get their opinion on the issue.<br>
&lt;TabAtkins> Rossen_: So postpone to next week?<br>
&lt;TabAtkins> TabAtkins: Alternative is resolve pending objections<br>
&lt;TabAtkins> fantasai: I don't udnerstand enough to know if there might be objections<br>
&lt;TabAtkins> fantasai: But i'm okay to resolve if it's clear that we might reopen<br>
&lt;TabAtkins> RESOLVED: change backdrop-filter's edgeMode to mirror, pending any objections<br>
