Is this possibly related to T413356: On Wikimedia Commons: Uncaught TypeError: can't access property "getSelection", surface is null?

This error is still occurring after the fix to T413356 (https://logstash.wikimedia.org/goto/850735079dfa30a98286ea7e8d4a186a) at a lower volume, so likely related but not identical.
