I have a working angular project with metronic 9.21. I now want (need) the bugfixes from 9.3.1. I tried using the files from metronic-tailwind-html-demos/dist/assets and overwriting my local files with these.

Now I get many syntax warnings from the styles.css:

Expected identifier but found "&" [css-syntax-error]

src/assets/css/styles.css:6169:39:
6169 │ .kt-menu-item.show > .kt-menu-link.& {

These errors makes sense, as css does not have "&" as a feature. why is this in there?! My older styles.css from 9.21 has valid code like:

.kt-menu-item-show\:text-foreground.kt-menu-item.show,
.kt-menu-item.show>.kt-menu-link .kt-menu-item-show\:text-foreground,
.kt-menu-item.show>.kt-menu-label .kt-menu-item-show\:text-foreground,
.kt-menu-item.show>.kt-menu-toggle .kt-menu-item-show\:text-foreground {
color: var(--foreground)
}

I cant update with these errors.
