Chrome Task manager not coming to foreground

After being frustrated by this for weeks, I figured out the problem and it seems like a bug on Chrome's side. Actually it was coming up in the foreground just not in the visible space of the primary monitor. I noticed that there was something going into the left side of the screen.

So, to correct the problem I connected an additional monitor and made it extend to the left side of the primary monitor and there it was. I repositioned it to the primary window and it comes up fine now. Though I still don't get how it ended up there in the first place and even after reinstalls why it wasn't adjusting it's position to the primary monitor.

Edit: As kinokijuf commented a better way would be to use Alt-Space to move the screen back on to the main screen.

A variation on what kinokijuf suggested: I wasn't able to move the Chrome Task Manager using the Alt+Space technique. However, I was able to maximize it using the Alt+Space Technique, and then I just snapped it back to it's former place and it works fine now.
