Height of editing pane too low

Describe the bug

When editing a contact in the browser the height of the <div> with class splitpanes__pane splitpanes__pane-details is too low. If you want to add additional fields the dropdown for choosing the new field type is cropped. Or if you want to edit a date field the date picker's OK button sometimes can also be cropped by it.

Here is a screenshot showing the issue:

Steps to reproduce

1. Open a random contact
2. Click on 'Add new property...' (German: 'Neue Eigenschaft hinzufügen')
3. The dropdown menu often is cropped.

Expected behavior

The dropdown menu should be visible completely.

Actual behavior

The bottom end is not visible all the time. You need to scroll down in the parent div and the dropdown box itself.

Start by reproducing the contact editor issue and inspect the div with class splitpanes__pane splitpanes__pane-details in the browser. Verify the Add new property dropdown and date picker’s OK button remain fully visible without scrolling the parent or dropdown.
