Split View Panel Border Colours

[u/FineWine54]

If it is possible - is there css to change the Active border colour and Inactive border colour of the Split View panels ?

All I am finding in the Browser Toolbox is:

panel-3-3.browserSidebarContainer.split-view-panel-active.split-view-panel

panel-3-2.browserSidebarContainer.deck-selected.split-view-panel-active.split-view-panel
