@starting-style is reported as an unknown at rule by svelte-check

[simpliston]

Describe the bug

If I use @starting-style, svelte-check reports it as an unknown at rule:

Warn: Unknown at rule @starting-style (css)

                        @starting-style {
                                opacity: 0;

This is not reported as an unknown at rule by stylelint or biomejs

Reproduction

In any .svelte file in a svelte project, use @starting-style. Run svelte-check

Expected behaviour

The at rule should be recognized and not reported as unknown
