-----------
Fix #27849: 3D manipulator widget lost on mesh in edge mode.

The manipulator was always using vertex selection flags, but those are only
valid in vertex mode, as selection flag flushing only happens in the direction
vertex -> edge -> face. Now use edge/face selection flags when needed.
