The Bug:

You cannot click on an area to set a value within the spawn protection slider in the realms world options menu.

Upon clicking on an area within a slider, the slider's value will be changed to the position of your mouse cursor; this works for every slider other than the spawn protection slider in the realms world options menu.

Steps to Reproduce:

1. Navigate to the minecraft realms menu.
2. Click on your realm and hit the "Configure" button.
3. Hit the "World options" button.
4. Use your cursor to click on any area within the spawn protection slider that the slider isn't already on.
5. Take note as to whether or not you cannot click on an area to set a value within the spawn protection slider in the realms world options menu.

Observed Behavior:

You cannot click on an area within the spawn protection slider to set a value.

Expected Behavior:

You would be able to click on an area within the spawn protection slider to set a value.
