CSS issue - background-color: transparent changes to background-color: initial

[coliff]

Hey there. I noticed what I think is a bug. Bootstrap 5 has a .bg-transparent class which has the properties:

background-color: transparent !important;

However, minify (via Hugo v80.0) changes this to:

background-color:initial!important

background-color: initial isn't supported by Internet Explorer 11. IE11 still has approx 2% desktop browser marketshare so I don't think minify should make breaking changes to CSS for IE users.

Thanks, this should be fixed using the KeepCSS2 option!
