Proposed changes

Improves usage of the user-select CSS property by using SCSS mixins whenever user-selection customization is required, ensuring consistent behavior across all browsers. Previously, that wouldn't work in some places with Safari, because it only supports the -webkit-user-select property that was missing in the code.

Additionally, it removes obsolete vendor-prefixed code related to that property.
