	################################### z-index explainer ###################################

	Tabs have various levels of z-index depending on state, typically:
	- scrollbar should be above all
	- sticky (compact, shrink) tabs need to be above non-sticky tabs for scroll under effect
	including non-sticky tabs-top borders, otherwise these borders would not scroll under
	(https://github.com/microsoft/vscode/issues/111641)
	- bottom-border needs to be above tabs bottom border to win but also support sticky tabs
	(https://github.com/microsoft/vscode/issues/99084) <- this currently cannot be done and
	is still broken. putting sticky-tabs above tabs bottom border would not render this
	border at all for sticky tabs.

	On top of that there is 2 borders with a z-index for a general border below tabs
	- tabs bottom border
	- editor title bottom border (when breadcrumbs are disabled, this border will appear
	same as tabs bottom border)

	The following tabls shows the current stacking order:

	[z-index] 	[kind]
			7 	scrollbar
			6	active-tab border-bottom
			5	tabs, title border bottom
			4	sticky-tab
			2  	active/dirty-tab border top
			0   tab
