I que for ARAM and Tab out to watch a stream while waiting, suddenly I'm in loading screen...

Aka, I never even got the message "A group has been found, will you join it?" as you normally would, I just went from waiting for the que to pop to automatically entering lobby without any warning whatsoever, it didn't tab back automatically, the client didn't alert me, I was apparently locked in as Taric with full AP carry runes in a horrible team composition and I couldn't do anything about it, like reroll, because I didn't even know the que had popped to begin with.

The first thing I see when the screen finally decides to tab back automatically is the loading screen with everyones boarders etc, where I see I'm loading into game with Taric apparently lol...

Has this been happening to anyone else? What the hell Riot... when que times end up being 15+ minutes for just a normal draft, you cant afford to have shitty bugs like this happen so that we can't even tab out during the wait...
