If the parameter is clicked then it should jump on the right side, but if on the right a new field is in focus the sidebar should also scroll to match and highlight the current parameter.

@Lena_WMDE @Sarai-WMDE What should be the correct behaviour if a user is also using the search filter in the left sidebar? In this case when focusing at the right side the respective item on the left might not be visible in the menu list.

Example:

This is especially relevant because the checkbox is the only place where a parameter can be deactivated.

Possible ways to fix this:

1. re-introduce the delete parameter button on the right side (does not solve the link problem)
2. change behaviour of the filter: always display all parameters but hightlight the matching ones (maybe also change order)

I hear this was already discussed, so please feel free to ignore my suggestion:

• Given that the filter is in use, when a content pane field is focused that is hidden in the sidebar, then the sidebar should scroll to the last visible field to precede the chosen field, and nothing should be highlighted.
• When the filter is reset, the selected field should be scrolled to and highlighted in the sidebar. This provides access to "delete".

I think there were some criteria missing, or I misunderstood the point of this task. New task T289043 was created because the highlight sync is very much not working yet. I'm guessing that my confusion is about "focus" vs. "highlight"...
