SVG and `:not` interaction cause .svelte-id class to not be applied

[WaltzingPenguin]

Describe the bug

CSS rules with :not are not being applied to elements inside of an SVG.

circle:not(.class-name) { /* Is not applied */ }

As a workaround, adding this to the style block causes things to work as expected:

circle { /* Doesn't even have to contain rules */ }
