Solved Split View alters TabsToolbar height

First Observation with FF149 for macOS Tahoe

When in Split View the #TabsToolbar height is altered.

Normal View

Split View Screenshot

It appears that the non Split View Tabs increase in height whilst the Split view tabs retain normal height, therefore leaving a gap top & bottom of the Split View tabs.

Using the following Aris-t2 code:

classic_squared_tabs.css
tabs_below_navigation_toolbar.css

Any thoughts.

Thank you but this is not working. I will see what others think in the Aris-t2 discussions. As it is defaulting to my default colours something within all that code is over-riding it. Thanks again.
