Fix multiline attributes processing in doctest

Fixes #97440.

It seems like the call to `check_if_attr_is_complete` is not provided with the correct argument: the pending attribute should be passed, while the current line is actually being passed. This causes any attribute with more than 2 lines to fail and produces ICE when running through doctest.
