Bug report

276afa3

This is in the same vein as #3406, but instead occurs when the abstract method comes from a grandparent class instead of the parent.

Code snippet that reproduces the problem

I've put together a sample repository here with a README: https://github.com/dktapps/phpstan-traits-abstract-bug-test

alternatively, here's a phpstan.org snippet: https://phpstan.org/r/81de903f-e93c-4b49-896a-757e67d793e7

Expected output

No error should be reported.
