We had this issue before in #559 and fixed it in b2f3cd1 (no PR, pushed to main by accident). This fix still works.
But what I see now is that in some cases it does not: It works for the Bifrost "spectrum view". It does not work for the TBL multi-blade detector view. I spent 3 hours trying to reproduce this, including all possible combinations of coords and their properties, shapes, and using a saved version of the data. No luck. Neither I nor Claude have any idea what is going on.
Edit: Since then I also found that the Estia multi-blade detector, which has a different shape, does not appear to have this issue.
