We encountered a bug with vue/ts in our configuration: If we re-export a vue component, it will be typed to any if used inside Vue's <template>. Disabling this typescript rule restores the expected typing. Github issue link: vuejs/core#11732 This also uncovered that radix didn't adhere to our typing rules, we silenced those errors.

Steps to reproduce
In the provided link, toggle the noPropertyAccessFromIndexSignature rule in the tsconfig.json.
What is expected?
The rule should not have an effect on the typing of Comp in the template block.
What is actually happening?
When turned on, the Component exported from index.ts will be typed as Any (only inside the template block, though!). This will silence the typing error present in the example.
System Info
No response
Any additional comments?
This error hid a number of typing errors on our site. Trying to reproduce it showed that in fact it's this rule which affects the behavior.
