[rozbrajaczpoziomow]

Describe the bug
The CSS Editor moves the cursor forward, yet it still edits before the cursor if the font is different

To Reproduce
Settings -> Custom CSS ->

* {
    font-family: 'Comic Sans MS' !important;
}

And propably turn on liveupdate

Expected behavior
For the cursor not to be displaced

Screenshots
I didn't move the cursor: I just clicked backspace for the screenshots

System Information:

1. Don't use the universal selector to change your font, ask for help in the #custom-css channel to know how to properly do it
2. This is not an issue with the installer

Please see above. In the end this would be an issue with the Monaco editor, not BD itself.
