fix(runtime-core): type ExposedKeys removed defined properties on com…

[akotulu]

Fixes typo made in pull request #3399.

IDEs using Vue language service with TypeScript support will have all the local component variables displayed as red with an error Vue: X does not exist on type. ExposedKeys will compare empty string ('') to extend Exposed type which will always fail cause builtin string can't extend custom class.

Tested with:
PHPStrom 2024.3.1.1
TypeScript 5.7.3
Vue LS 2.2.0

This change will break the existing test case in packages-private/dts-test/defineComponent.test-d.tsx. You can verify this by running pnpm run test-dts.

By the way, could you provide a test case or a minimal reproduction to clarify the issue this PR is addressing? Thanks!

I can confirm this issue using Webstorm LTS 2024.2.5 Build #WS-242.24807.6
I created a reproduction repo: https://github.com/DC240/12697-runtime-core-error-reproduction

It is however, only the case if I'm using class based components using vue-facing-decorator. Using the composition API, the component resolves correctly. We have a lot of older projects at our company for which there is no budget to convert them to composition API, so for us it is a pretty common and annoying problem.

It took whole weekend to figure out where this issue with Intellij ideas came from. I will look at the tests when I have time again. Probably end of the week.

Do you have any updates on this by any chance?

this change is not proper, both a and b should be exposed, see line 1618.

Trying to reproduce the issue weeks later fails with or without the modification. Language server doesn't display the errors anymore. There hasn't been any PHPStorm update, kinda of magic what is going on. Also thanks for pointing out the test was invalid, should have read the docks more carefully beforehand.
