Caused by rB2ba1cf4b40fc: Fix T78880: UV Editor - Match prop edit connected behavior with mesh editing…, rB9681708c1cf1: Fix T80561: Crash when multi-mesh editing UVs with proportional editing was not enough to fix

Short description of error
When multiple objects are edited at the same time, editing their UVs causes a crash. If not immedietly when clicking an UV set atleast after couple clicks.

Exact steps for others to reproduce the error

Open attached .blend file
Click one object and then Shift+Click the second
Tab to edit mode
In UV editor in vertex mode select a vertex
Press G, it crashes either immediately or after couple moves

There was T80561: Crashing when I alter UVs in multi-mesh editing (using proportional editing), but apparently the fix was not enough.

At least it asserts for me with the file from the report (checked the meshes, thy are valid afaict)

BLI_assert(BM_elem_flag_test(l, BM_ELEM_TAG) == 0);
