Prevent TOC from collapsing (returning to top) when using tabs in rmarkdown

Question

In rmarkdown, when using a floating TOC and nested tabs I have come across an issue where the TOC goes back to the 'top' tab. For example, If I am viewing the Even more details about Bar here subtab within the Bar tab and I click on the content in TOC for within that subtab, it then proceeds to collapse the TOC and goes back to the 'top' tab. Alternatively, if I click on the header for a subtab within the TOC, the TOC will collapse back to the 'top' tab once I began to scroll. Example code below.

Is it possible to prevent the "unrequested" collapsing of the TOC / returning to the 'top' tab, anchor the TOC to the current tab or subtab? Or, is it possible for the TOC to only display TOC items for the current tab or subtab to prevent this issue?
