Code Snippet

Example of the types in question:

Describe the bug

I'm no longer able to define working types for custom matchers for locators and pages following the same pattern as the generic example in https://playwright.dev/docs/test-configuration#add-custom-matchers-using-expectextend. This was previously working.

I suspect this is related to the introduction of SpecificMatchers in 81cc39e.

It's possible the documentation needs to be updated/expanded, but I'm not sure it's still possible to add custom matchers for pages and locators (and API responses...)
