drag a tab to split-screen is broken

[Bdsrev]

Have a few tabs open, then click and drag one of them to either side of the screen so that tab detaches into its own window and is split screen. Notice that tab you dragged to either side of the screen is maximized. This is incorrect! Here's a screenshot of what it looks like.

I appreciate your response. Thanks. The teams at Microsoft must be very separated. Are Edge mobile and desktop also separated?

This still repros in Canary :( Seeing as Windows 11 is about quality and polish, can this be bumped up the priority list please? I know that Microsoft is putting a lot of emphasis on split screen these days, and this is a split screen issue
