@container rule output none

[a-d-w-s]

If I use @container then clean-css clears it on the output.

Input CSS

@container layout-fieldset (inline-size > 1500px) {
	.grid {
		grid-template-columns: repeat(7, 1fr);
	}
}

Actual output CSS

none

Expected output CSS

@container layout-fieldset (inline-size > 1500px) {
	.grid {
		grid-template-columns: repeat(7, 1fr);
	}
}

Not facing this issue on version 5.3.3 released 8 days ago.

Sorry, I used to "gulp-clean-css": "^4.3.0",
Now I used clean-css directly and everything works.
