"Reduce motion" is a setting to reduce animations, in my understanding especially those that can induce feeling of 3D motion and cause "not feeling well" state.

Tab Tray currently animates the tab in a sense that makes it feel "zoom out" into the Tab Tray, and then when selecting it, the selected tab web content "zooms in", thus this could create a perception of movement for the observing individual.

We should take a hint from App Switcher (which is in principle very similar to Tab Tray) to make e.g. a crossfade animation in/out of the Tab Tray instead of the "flying tabs" in case where the user has turned on the "General > Accessibility > Reduce Motion > Reduce Motion" setting.

Note that Safari does not do this with their tabs, so we would be better than Safari in that regard.

What prevents this from landing?
Looks like Boris left some comments for review for arkratos to address. This code is also pretty stale since in the meantime there has been a lot of work done on the transition animation code. I can probably update this - doesn't seem to be a lot of code changes.

Would be great if this were moved ahead with the other issues in VIMS. There's been movement in the W3C on this
