* Nesting: `mx_ResizeHandle`
* Nesting: `> div`
* Run prettier
* Use a custom property
* Remove a redundant declaration: `cursor: row-resize`
The resizer is either vertical or horizontal, and since `cursor: row-resize` is applied by default, it does not need to be repeated here.
* Conform the class names to the naming policy
* Revert "Use a custom property"
