The object deselects and the spin does not work

Thanks for the report.

Single click with left mouse button on viewport will try to find the hit (to select the object element). Selected elements will reset the BM_ELEM_SELECT flag if no near hit is found.

Hold and drag is working in case of selected elements are not null. So I don't think this is a bug or regression.

I will close the report since working is same for versions 2.83 and above.

If problem is not fixed then please add a short video to describe the exact issue.

(Just my understanding from code, developers can correct if the explanation is wrong)

I'm sorry to show you a video. The spin does not work!
Watch the following video

On the previous version, it works!
