Restrict Token Movement for grouped tokens

The new restricted movement feature is great, but don't work fine for grouped tokens : it works for the group movement itself, but if you move a token "inside" the group (mousedown and drag), it can go on a forbidden area.

Logged in as player. Yes, the selected token as "Has Sight" box checked.

campaign 216116/pendragon-gpc Logged in as player, you can control the group horse + red&white shield at the bottom lef corner of the map. Sight and movement are restricted to the outside, inside of houses must be forbidden. If you move the group with click (down and up) then mousedown &drag &drop, all is fine, you can't go into the house. if you move the shield only (mousedown without mouseup then drag & drop), you can go inside the house:

If you ungroup and have a player move the shield, can it still move through the house walls?

No, it seems to be linked to an inner move "inside" a group.
