@A5rocks, @so1ve merged, well done! Next we can add highlighting to the target tag of fallthrough attributes.

Since this feature would significantly impact type checking speed, this feature was changed in ebb8490 to require fallthroughAttributes to be explicitly enabled in tsconfig.

This is a minimal reproduction of the case of slow tsc when fallthroughAttributes is enabled.

import { defineComponent } from 'vue';

const Foo = defineComponent({
	props: {} as __VLS_TypePropsToOption<{ bar?: string }>,
});
const Bar = defineComponent({
	props: {} as __VLS_TypePropsToOption<FooAttrs>,
});
defineComponent({
	setup() {
		return {};
	},
	props: {} as __VLS_TypePropsToOption<BarAttrs>,
});

type FooAttrs = __VLS_OmitIndexSignature<Partial<InstanceType<typeof Foo>['$props']>>;
type BarAttrs = __VLS_OmitIndexSignature<Partial<InstanceType<typeof Bar>['$props']>>;

type __VLS_TypePropsToOption<T> = {
	[K in keyof T]-?: {} extends Pick<T, K>
	? { type: import('vue').PropType<T[K]> }
	: { type: import('vue').PropType<T[K]>, required: true }
};
type __VLS_OmitIndexSignature<T> = { [K in keyof T as {} extends Record<K, unknown> ? never : K]: T[K]; };

Just a question: it seems that when having strictTemplates and fallthroughAttributes both enabled on vueCompilerOptions, when some emits are defined on a component and trying to use native events binding on that component (ie: @click), vue-tsc is complaining about that. When configured in this way, is it fine that it complains about that? Should I forward native events that I want to use on my component?
