Importing multiple .ics files at once pushes the list of events offscreen

Steps to reproduce

1. Click on Calendar Settings
2. Choose Import calendar
3. Select over 15 .ics files (if you're screen has higher resolution you'd need to select even more files)
4. See bug

Expected behavior

Perhaps when importing multiple .ics files the pop-up screen for importing them should allow scrolling throught the multiple events.

Actual behaviour

See screenshot. Issue is found at the bottom of the pop-up screen. See how it goes beyon the pop-up screen so you can't choose the "Calendar to import into" for events that are hidden.

Start in Calendar Settings > Import calendar and reproduce the issue by selecting more than 15 .ics files. The work is done when the import popup lets users scroll through all events and keeps the “Calendar to import into” control reachable.
