Bug: write enable locked in project but not mixer

When a group track is in a folder and you lock the folder (with the folder icon on the folder track) the group’s write enable button grays out so you can’t click it. However, in the mixer said group has a working write enable button regardless of the project window write enable being grayed out (LOCKED). This logic doesn’t make sense… either it’s locked or it isn’t. Note that even though mixer write is enabled writing does not occur while folder track is locked.

Note the group itself does not have a lock icon like all the other tracks, but I don’t understand why not?
