===Problem
The Interaction Timeline returns only partial results for queries on users who have high editcounts:
* https://tools.wmflabs.org/interaction-timeline/?wiki=enwiki&user=Missvain&user=Hullaballoo%20Wolfowitz
* https://tools.wmflabs.org/interaction-timeline/?wiki=enwiki&user=Mitchumch&user=Kaldari
* https://tools.wmflabs.org/interaction-timeline/?wiki=enwiki&user=Samf4u&user=Galobtter
* https://tools.wmflabs.org/interaction-timeline/?wiki=enwiki&user=NinjaRobotPirate&user=Erik (as [[https://en.wikipedia.org/w/index.php?title=Wikipedia_talk%3ACommunity_health_initiative_on_English_Wikipedia%2FInteraction_Timeline&type=revision&diff=810871348&oldid=810854269|reported here]])
===Acceptance criteria
* The tool should continue to paginate as needed to return all results for a query. If we need to transition to "Load more" button-based pagination, we should.
