isCustomElement to use Shoelace components

[graceyoung-ww]

I'm doing some tests with Shoelace 2.0, and I'm able to get it working just fine when the <sl- component is in the root app (main.html), but the app.config.compilerOptions.isCustomElement = (tag) => tag.startsWith('sl-') is being ignored for any components loaded using vue3-sfc-loader.

This results in the components working just fine, but a bunch of runtime compiler warnings appearing in console.

Is there a way to get the isCustomElement method to be honoured by vue3-sfc-loader?
