**List of steps to reproduce** (step by step, including full links if applicable):
* add a page to your watchlist
* make an edit and in the edit summary use a very long word without a single space to that page
* open your watchlist or recent changes pages
**What happens?**:
* The contents of the edit summary overflow the viewport
**What should have happened instead?**:
* The contents should have wrapped
This happens because this element is floated and will therefore grow unless bounded with max-width

- Confirm that the summaries on https://en.m.wikipedia.beta.wmflabs.org/wiki/Special:Contributions/Jdlrobson do not wrap
- Watch the page https://en.m.wikipedia.beta.wmflabs.org/wiki/Selenium_Echo_mention_test_0.32663851022409507 and find the same edit on your watchlist and check it doesn't wrap there https://en.m.wikipedia.beta.wmflabs.org/wiki/Special:Watchlist?hidepreviousrevisions=1&hidecategorization=1&hideWikibase=1&limit=50&days=7&enhanced=1&urlversion=2
