    This might help (largely inspired from here). The idea is to rewrite the HTML code of tabsets from scratch (using htmltools) and define the same class for each tab item: 'tab-pane active'. The drawback of this approach is that it makes both plots visible before clicking on a tab. To solve this issue, we can add a JS script as a workaround that waits 1 millisecond before automatically switching to a tab.

    If you add the following code to the end of your example, the appropriate text-anchors will be set whenever a tab is clicked/activated, which should solve your specific problem...

    ```{js}
    setTimeout(function () {
        $('.nav-tabs a').on('shown.bs.tab', function() { 
            d3.selectAll(".node text").attr("text-anchor", "begin").attr("x", 20);
          })
      }, 1)
    ```
    

    You could also then remove all of your calls to onRender further up since they're no longer needed.

    Here's a full example with a bit of reformatting to make it more concise...
