Tab buttons scroll back when turbo frames are lazy loaded

[Timmitry]

Describe the bug

I'm using tabs on a show page. Inside the tabs are has_many fields. There are many tab buttons, so that a horizontal scrollbar appears. When I scroll to the right and press a tab button for the first time, the corresponding tabpanel appears and lazy loads the content. When this happens, the horizontal scroll on the tab buttons resets to the left, and I need to scroll back to the right.

This does not happen if the content was already loaded, e.g. when clicking for the second time on a button.

As a side note: When clicking a tab button on the far left or far right, a horizontal scroll is applied automatically, to make the next button visible. Even though I understand why this behaviour was added, I feel that it is rather a bit annoying, as I always have to check where I was before clicking the next button. I think it would be easier to click through the tabs if the horizontal scroll just stayed where it was 🙂

Reproduction repository for the bug

No repository, but mainly just this code:

        tabs do
          public_profile_panel
          personal_information_panel
          employee_information_panel
          bank_account_information_panel
          payroll_information_panel

          field :user_contract_details, as: :has_many, translation_key: "activerecord.models.user_contract_details"
          field :user_vehicles, as: :has_many, translation_key: "activerecord.models.user_vehicle"
          field :absences, as: :has_many, translation_key: "activerecord.models.absence"
          field :user_locations, as: :has_many, translation_key: "activerecord.models.user_location"
          field :user_equipments, as: :has_many, translation_key: "activerecord.models.user_equipment"
          field :project_teams, as: :has_many, translation_key: "activerecord.models.project_team.other"
        end

Expected behavior

I don't want the tab button list to move at all 😉
