Does docking tabs support something like ImGuiTabBarFlags_FittingPolicyScroll?

No.

If you modify the code in DockNodeUpdateTabBar() to add the ImGuiTabBarFlags_FittingPolicyScroll scroll to the tab bar:

ImGuiTabBarFlags tab_bar_flags = ImGuiTabBarFlags_Reorderable | ImGuiTabBarFlags_AutoSelectNewTabs;
tab_bar_flags |= ImGuiTabBarFlags_SaveSettings | ImGuiTabBarFlags_DockNode;
tab_bar_flags |= ImGuiTabBarFlags_FittingPolicyScroll;

It seems to work:

However I don't know what would be a suitable design here.
We could have a global style setting to specify the default for tab bars created by the docking system., however I don't think always-on scrolling behavior is very desirable.

I like the idea of a global style for the tabs and also agree that always on scroll is not desirable. Generally we probably only want scrolling if the tabs take up more room than we have to display...
But do we know that before we render?

This is already the case, but I don't think that's sufficient. The ideal solution would combine both shrinking and scrolling.
