[5.x]: More than one default can be selected for Dropdown fields

[MoritzLost]

What happened?

Description

When editing an existing Dropdown field, I can have more than one option selected as the default. After selecting a third option, the second one will be cleared out. And after deselecting the previously saved option, only one option is active at the time. But after reloading the page, I can select an additional default option, and save the field like that.

Steps to reproduce

1. Create a radio field, define some options and select a default.
2. Save and reload the page. Mark another option as default.

Expected behavior

Only one default option should be selectable.

Actual behavior

After a page reload, I can have two default options active at the same time.
