[🐞] [v2] Context breaks when using higher order components in CSR

[thejackshelton]

Which component is affected?

Qwik Runtime

Describe the bug

When using CSR and context, where a component relies on a lower level primitive / component that also uses context, nothing is rendered and we see Qwik Error 8.

SSR this behavior works.

For example, say you have a Checklist component that uses context, and each Checklist item returns a checkbox that uses context, then that behavior is broken in CSR.

The problem here is provided context is never a parent for the errored child.
the CheckboxTrigger is using context but its never projected, so never have parent with useContextProvider
Not sure if this is a bug

however with Slot it is still failing

At the very least there is an uncaught bug with the same error in the QDS project.

https://github.com/kunai-consulting/qwik-design-system/blob/v2-migration/libs/components/src/checklist/checklist.browser.tsx

These tests were all passing on a previous v2 version, upgrading caused Qwik Error 8 in a similar fashion to the minimal reproduction. These are valid patterns we've been using in production in v1.

Also the playground link is not loading for me. It is an endless loading spinner.

I am unfortunately still running into this error with latest on build/v2. @Varixo have some time to pair / take a look at my tests?
