User-Select: all is not supported in IE or Edge Legacy

Created by: coliff

The Text Selection .user-select-all is not supported in IE or Edge Legacy. REF: https://caniuse.com/mdn-css_properties_user-select_all

Maybe it could mention this as a note on on the v4 docs? https://getbootstrap.com/docs/4.5/utilities/interactions/#text-selection

The compiled CSS actually includes:

.user-select-all {
  -ms-user-select: all !important;

but it doesn't do anything. Not really a big deal since it'd make almost no difference to the file-size after gzip compression - but Can that be excluded from the CSS? Or would this be an issue with Autoprefixer?
