Research direction
First, read the testharness documentation at http://web platform tests.org/writing tests/testharness.html and the linked pull requests #6792 and #10599. Understand how the 'global' key is currently handled. Then look at the relevant code in the repository (likely testharness.js or similar) to identify where META lines are parsed. The issue asks for supporting multiple META lines for keys that accept multiple values, like 'global'. Propose a solution that can parse multiple lines and combine values.
