[Solid, React?] If `beforeLoad` is a sync function, context is not merged

[elite174]

Which project does this relate to?

Router

Describe the bug

The thing is that beforeLoad function MUST return promise for having correct context for child components. If it's synchronous, then child function may not see the context, so here's either typescript bug (which allows to pass sync function to beforeLoad) or context merge bug.

Steps to Reproduce the Bug or Issue
