NOTE: in face select mode, there was also a comment to check UV selection (instead of just picking the active face) which is now added. This became more of a problem for multi-edit since many could have an active (but unselected) face which made shortest path picking start from that active unselected face (which just seems unituitive in pratice.

NOTE: we are intentionally not breaking out of the objects loop after one successful path picking. So having (selected) active elements in multiple objects might end up picking shortest paths on both. Reason is that atm., UV_NEAREST_HIT_INIT_MAX is used for finding nearest elements (as opposed to UV_NEAREST_HIT_INIT_DIST_PX) which will make the second click successful even for far away selections in other objects [so breaking early might actually do the shortest path on one object but return early before picking shortest path on the object one was actually interested in]. This is debatable, UV_NEAREST_HIT_INIT_DIST_PX can have problems when zoomed in for edges and faces even with high values. So for now, allow for selections in multiple objects (even though it breaks redo for all but the first object).
