Oscilloscope: After drawing cursors, pressing Ctrl+Z and/or Escape should reset the view

[DeflateAwning]

Is your feature request related to a problem? Please describe.
I'm frustrated that I can't figure out how to reset the view after drawing cursors!

Describe the solution you'd like
I want all of the following to reset to my last view before I drew the cursors:

1. Pressing Ctrl+Z
2. Pressing Escape
3. Clicking a large button that appears to the left of "Print" and "Enable Mixed Signal View". This button should say " Undo Cursor Zoom"
4. Back button on a mouse with forwards/back navigation buttons.

Describe alternatives you've considered
I still can't figure out how you're supposed to get back. It almost feels like a bug.
