im trying move spell from spellbook to hotbar and i get this error from omnibar preventing it and i have to disable the addon

i dont know why omnibar would interact with spellbook but it seems it does

anyways just reporting this, ive seen it few times in other occasions pop up when playing arena too

2x [ADDON_ACTION_FORBIDDEN] AddOn 'OmniBar' tried to call the protected function 'CastSpell()'.
[string "@!BugGrabber/BugGrabber.lua"]:480: in function <!BugGrabber/BugGrabber.lua:480>
[string "=[C]"]: in function `CastSpell'
[string "@FrameXML/SpellBookFrame.lua"]:713: in function <FrameXML/SpellBookFrame.lua:660>

I'm seeing this as well, it happens on the first spell book click after logging in, if you reload it goes away
