Steps to reproduce

I am trying to get Vue3 running on an 2017 TV model of LG with vue-reactivity-polyfill and vue3-plugin-polyfill

Browser running on the TV is: Mozilla/5.0 (Web0S; Linux/SmartTV) AppleWebKit/537.36 (KHTML, like Gecko) QtWebEngine/5.2.1 Chrome/38.0.2125.122 Safari/537.36 WebAppManager

What is expected?

It should run with no errors

What is actually happening?

It breaks with errors

A workaround that works for me is adding these extra checks:

1. The reproduction link doesn't point to a reproduction
2. We don't maintain or support the plugins mentioned.
3. Vue 3 doesn't support that browser.
4. Various features we use in Vue 3 can't be fully polyfilled
5. The proposed workarounds will inevitably lead to other bugs.

I'd recomment opening an issue at one of the repos you are using.
