Fix wrap test

This EditorOptionHandlers unit test fails for me every time:

"should also wrap long lines in inline editor by default"
```
Error: Expected 30 to be less than 30.

I seem to be the only one seeing this. I think it has something to do with the combination of:
* My new Windows HiDPI laptop (1920x1200)
* Recent change where test windows no longer inherit user options (i.e. font size zoom)
* Test windows seem to be wider now

So, the line of code is not wrapping lines any more. I checked in a fix in PR #7289 for a similar test that no longer was scrolling horizontally.
