Fix T77417: Topology Automasking not working with individual vertices 

The flood fill operation was setting the mask using to_v, so in the first
iteration when the floodfill callback was using the active vertex as
from_v and any other neighbor as to_v, the mask for the active vertex
was never set.

Now the mask is set using from_v and it checks if it should continue
propagating to the next neighbor using to_v.
