page_cache error " '@returns' tag is not defined."

Thank you for reporting.

Can you provide more details for how you are seeing this?

Wonder if there should be a rule for catching these, as there are about 60+ in core.

I just encountered it, when debugging the page_cache module in Visual Studio Code. See attachment.
(since I really do not understand why caching between authorized and anonymous users is so different).
I am not sure which extension picks this up.

I find more locations where core does not adhere to coder rules. Some day, I will report them.
