If style block has `global` attribute, reverted styles don't update until page refresh

[JohnnyFun]

Describe the bug

In my svelte.config.js, I'm using globalStyle. If I make a css change to a style tag with a global attribute, the app updates via HMR as expected, but if I revert the change, the app doesn't re-update to show the initial styling.

This might actually be an issue at the svelte-loader level. Looks like it happens if I explicitly use :global too and get rid of the global style attribute.
