Go to https://en.wikipedia.org/wiki/Special:LintErrors/large-tables and manually review those tables flagged.
We are looking for tables that break out of the limited width and/or on mobile break the viewport. Identify false positives and note down what is common between them.
Go to https://en.wikipedia.org/wiki/Special:LintErrors/missing-end-tag-in-heading and review the pages flagged (Created in T308398). If it appears to be working take next steps to make this visible to end users.
# Outcome
* Document how we can improve the linting. What characteristics of table can we filter out?
* On T66577 comment with some examples that were correctly identified by the linter and start a thread around ways we might improve those. Would horizontal scrolling be applicable or would it not make sense here?
* Create patch or task to show missing-end-tag-in-heading to end users.
