Comment 4 for bug 1531133

So I just had two instances of this:

1. I went to make some food. Spent 5-10 min away from PC, I guess. A few minutes after I came back I was prompted to TaB.

2. Watched a 40 min long video on YT, didn't touch anything for I' guessing the last 30 mins of it. At the very end of it, right before the PC was put into sleep mode by Ubuntu because I hadn't touched it in so long, I was prompted to TaB.
