Previously, the provider guarded type inference with context.maySwitchToAST(func) where func is the test function that declares the parameter. If that context couldn’t switch to AST for the actual fixture function’s file (commonly conftest.py), context.getReturnType(fixtureFunc) wouldn’t look into the fixture body, so the return type degraded to unknown.
