When a new field group is defined and its name contains a space character, Page Builder edit view won't allow to switch groups to access its fields.

Steps to reproduce
1. Clean installation of Ibexa DXP v3.2/v3.3
2. Create a new Field Group called "User data".
ezplatform.yml

 ezplatform:
    repositories:
        default:
            fields_groups:
                list: [ content, user_data, metadata ]
                default: content

translations/ezplatform_fields_groups.en.yaml

content: Content
metadata: Metadata
user_data: User data 

3. Clear the cache manually:

rm -rf var/cache/* 

4. Log in to the back office as the admin user.
5. Add a new single-line field to the Landing Page Content Type. Set the new fields Category to "User data".
5. Edit Ibexa Digital Experience Platform Landing Page. In Page Builder's edit mode switch to fields view.
6. Click on "User data" tab.

Result
Nothing happens

Expected reuslt
Fields from the "User data" Field Group are displayed normally.
