Toxic Vines are disabling Frostblink Mines - intended behaviour?

Toxic Vines from Foul Ritual altars are disabling the throwing of Frostblink mines (Frostblink of Wintry Blast). I know toxic vines disable PLAYER movement skills, but afaik they are not supposed to affect skills on proxies, such as mines. When Toxic Vines are on my character I cannot throw Frostblink mines.

Please respond with whether or not this is intended behaviour.

If this is intended behaviour I think this feels very bad - it's unintuitive. Toxic vines should be limited to player skills and not proxies (if even kept as a mechanic at all).
