Should mobs still be able to regain concentration and continue casting while stunned?

Looks like it's flagged unstunnable. You can still 'stun' mobs flagged like that but they don't actually stun. E.g. giants and such. And the stun only gives a chance at interrupt, like a bash, it's not guaranteed.
