Description David Kilzer (:ddkilzer) 2022-12-09 17:40:33 PST

Fix use-after-move in WebCore::RealtimeMediaSource::supportsSizeAndFrameRate().

Both `width` and `height` have a use-after-move bug in Source/WebCore/platform/mediastream/RealtimeMediaSource.cpp:

```
    if (!supportsSizeAndFrameRate(WTFMove(width), WTFMove(height), WTFMove(frameRate))) {
        // Let's try without frame rate constraint if not mandatory.
        if (frameRateConstraint && !frameRateConstraint->isMandatory() && supportsSizeAndFrameRate(WTFMove(width), WTFMove(height), { }))
```
