Consistent selection elements in user settings (preferences)
Summary
Currently most of the input fields and selections are consistent, but in the user settings preferences only the language selection is consistent to most of the other places in GitLab. I would propose to use consistent elements for the selection of user settings on the frontend side.
This is not a bug, more an issue to harmonize the preferences page. I am not sure about internal processes and the roadmap on this, but most fields are like the language selection so the others should be converted to the same style/functionality.
Steps to reproduce
Go to the preference page (https://gitlab.com/profile/preferences), the selections except for the language are similar but differ from GitLab forms like issue creation as example.
