[Issue #U4-9073](http://issues.umbraco.org/issue/U4-9073)
In `grid.editors.config.js`, the style config for the Quote editor has an incorrect CSS style rule for italic, it has...
```css
font-variant: italic;
```
It should be...
```css
font-style: italic;
```
I wasn't sure which `grid.editors.config.js` to change, so I did them all.
