Variables Pane Interpreter Selector Out of Sync with Others

[samclark2015]

If multiple versions of a language have been utilized in a session, the variables pane continues to show inactive versions of the runtime.

In image above, Python 3.12 was initially activated and then switched to Python 3.11. As seen, Python 3.12 still appears.

Attempting to switch to an inactive interpreter version within the variables pane updates the top-bar interpreter dropdown; the console and variables pane selectors both stay on the current, running interpreter version. Additionally, duplicate entries for the same runtime version may appear under the variables pane selector.

Similarly, if the kernel is changed in a Notebook file, duplicate Notebook runtime entries appear in the runtime select in the variables pane.

Describe the issue:

See Above

Steps to reproduce the issue:

1. Start/activate Python (or R?) interpreter using top-bar interpreter drop down.
2. Start new interpreter using a different version of the same language.
3. Variables pane now shows both versions of the language in its selector. The originally activated runtime is broken.

Expected or desired behavior:

Interpreter options offered by the variables pane match what is active & available in the Console pane and main Interpreter dropdown.

Were there any error messages in the UI, Output panel, or Developer Tools console?

None

Is this the same as #3504?

It is a persistent bug. The unused/inactive runtime should be removed from the list

@jmcphers Yes - same thing. Apologies for the dupe!
