[2020] Not picking your cards with Ranger of Eos reveals all your library

Sorry for the lack of pictures or video. My stupid self just forgot to record this bug, and the game was over quickly after the bug.

I was playing white weenies on historic yesterday while explaining the game to my wife, and casted Ranger of Eos. While my library was showing, I took a long time explaining my choices of this and that card, ran out of time and passed the turn to my opponent automatically.

The bug happened there, as the top card of my library continued to be face up, like when you're playing Experimental Frenzy. I could even click on the library and see all the cards in the order I'd draw them!

I'll try to force this in a few moments and maybe come back with a video to back it up.
