Treeform'ing while dot'ed is bugged

[quenyar]

I noticed while fighting Crag spiders in EK on Green that if I cast Treeform (druid spell) while dot'ed with Poison (Crag spider proc) the spell lands and applies the regen part. However the root part isnt applied and as such I can run around as a tree! :confused:

Also there is no buff icon for the Treeform spell, so I cant cancel the spell (if I want to SoW my self). Only relogging cancels the spell effect.
