* 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" This reverts commit 6116939eec7d9e4220b89a638623e5876e143adf.
