Anti-Aliasing not working >= 1.66.0

It seems as though Anti-Aliasing has stopped working since version 1.66.0.

When reverting back to version 1.65.0, the AA seems to work as expected.

Version 1.65.0 - Anti-Aliasing working

Version 1.66.0 - Anti-Aliasing not working

Version 1.67.0 - Anti-Aliasing still not working

Consequently setting useBrowserRecommendedResolution: false resolves the issue. Is this a bug or not?

@craigp1231 it's not a bug, we changed the default behavior in 1.66. From CHANGES.md

• useBrowserRecommendedResolution flag in Viewer and CesiumWidget now defaults to true. This ensures Cesium rendering is fast and smooth by default across all devices. Set it to false to always render at native device resolution instead at the cost of performance on under-powered devices. #8548

Technically it's still not applying anti-aliasing, the aliasing is just less noticeable because it's rendering at higher resolution on high density displays. If you want to enable anti-aliasing as well you can set viewer.scene.postProcessStages.fxaa.enabled = true.
