Is there a way of making the Active Tab Border highlighted on top instead of at the bottom?

With the tab.activeBorder you can highlight the bottom of the active tab, but how do you highlight the top of the tab instead, like in Firefox's current design?

An example of highlighting with tab.activeBorder:

"workbench.colorCustomizations": {    // Can customize each aspect
    "[One Dark Pro]": {               // Optional
        "tab.activeBorder": "#0A84FF" // Active Tab Highlighting
    }
},
