Bug description

In guest-permissions it is possible to set an allowlist for guest-apps.

1. Error: Deactivating this Option isn't possible (setting isn't saved after changing).

2. Error: Allowlist-Entrys aren't fully visible and not fully readble

3. Error: When clicking in the field, the chosen entrys dissapear and a list of values opens, but none of them seems visibly chosen (no checkmarks visible).

4. Error: The Reset-Button doesn't work.

Guest-App V. 2.3.0 Nextcloud V. 25.0.3 Tried in Google Chrome 110.0.5481.77 64-bit Tried in Firefox 110.6 64-bit

Steps to reproduce

1. Open the Administrator-Settings
2. Open the general Guest-Settings
3. Disable the allow-list-setting, change to anoter menu-point and change back to guest-settings: the allow-list-setting is active again
4. Try to edit the allow-list (not all entrys are visible, when the textline exceeds the lengh of the field; by opening the dropdown-list the chosen entrys arent marked)
5. Thy to Rest the allow-list after editing.

Expected behavior

The user should be able to deaktivate the allow-list-setting. The user should be able to read all chosen entrys of the allow-list an all chosen entrys shoud be marked visible in the list. The Reset-Button shoud set the default-settings.
