Tangentially related.

After a restart, and after Finder has opened multi-tab windows I have open before, clicking on a tab can suddenly move my view and the window to another space.

Apparently different tabs in the same window can think they belong to different spaces.

Something (I perceive as) common to a lot of the (perceived) increase in Apple software glitches recently, is I cannot fathom the logic for which the bug makes any sense. It does not feel like I am seeing corner case bugs, but instead major "bad-model" code, revealing its poor design.
