Guake Ubuntu 19.04 changes screen when clicking outside the terminal on the other screen

**Describe the bug**

when Guake terminal is opened on a screen, and then I click outside the terminal on the second screen, Guake changes of screen as well. (I don't have this issue on Ubuntu 18.04)

**Expected behavior**

Once Guake is opened, it shouldn't change of screen automatically. We should close it and reopen it when the mouse is on the second screen, so Guake opens in the second screen.

**Actual behavior**

Guake changes automatically of screen

**To Reproduce**

- Have a multiple screen setup
- Ubuntu 19.04
- Open guake on a screen and click outside the terminal on the second screen
