Comment 2 for bug 1909567

Testing this more, the same issue did appear in v1.7 if you directly typed in the text field to change the size - the text field probably intercepts the Enter key before the canvas gets it. It's more noticeable now in 1.8 since pressing the +/- buttons puts your cursor in the text field, so now you always hit this issue.

A couple ideas would be:
- Pressing enter in one of these fields could "finish" editing the value, and return focus to the canvas
- Clicking on the canvas could remove focus from the text field
- Somehow change the key processing order so that the canvas can intercept it first. This would need careful testing to ensure there aren't any new issues introduced.
