Comment (by strk):

 The reason why snap to bottom-right edge isn't performed is because that
 lower-right edge was NOT within tolerance distance BEFORE the incoming
 edge was snapped to the vertex of the upper-left edge, but the current
 code doesn't go back to querying the database on next snapping iteration.

 The topology-oriented snap algorithm proposed in
 https://gitea.osgeo.org/postgis/postgis/pulls/184 did include a recursive
 database query. I'll see if that kind of snapping would fix this case.
