Tab-bar: How to show/reveal the hidden tab-bar space when Using Dynamic Native Tabs

[SevenFactors]

Hello,

I'm using the Dynamic Native Tabs code snippet, and this works well.
The issue I'm having is that the top space of the whole bar is now cut-off in such way that the color bar for containers does not show.

See image where the yellow outline of the selected tap is cutoff at the top.
How to add that extra space again?

Thanks.

After lots of going around I figured out the issue was that the firefox.exe process was not ending after exiting Firefox thus my set values for #main-window #titlebar were not taking effect.

For those who may run into this thread in the future and are having the same issue, make sure firefox.exe process is truly ends
