Very long Event Titles can mess up user interface (browser, month view)

Steps to reproduce

1. in the browser, define a very long calendar entry, like with 20 or 30 words
2. create 4-5 other entries for the same day (can be shorter)
3. change to month view
4. clicking "# more" results in the first entry now occupying the full window width (no line breaks, no scrollbars), the other entries are out of reach

Expected behavior

The long entry should be displayed with line breaks (preferred), and/or the window provide scrollbars to allow maneuvering through the various calendar entries of this day.

Actual behaviour

In the browser calendar's month view, on trying to expand the list of scheduled events, the long entry blocks the whole screen and doesn't allow seeing and accessing the other entries of this day anymore.

Reproduce the issue in the browser calendar's month view with a 20–30-word event and several other events on the same day, using the stated Firefox setup if available. Inspect the month-view “# more” event expansion entry point. Done means long titles wrap or the expanded list scrolls, while all events remain accessible.
