unbounded (wrap grows to fit every tab).
OptionalmodeWhat happens when tabs don't fit. Default 'dropdown' (today's free
path). 'wrap' requires the MultiRowTabsModule.
OptionalmruOrder the dropdown by most-recently-activated. Reserved for
AdvancedOverflowModule; ignored until present. Default: false.
OptionalsearchFilter input over the group's tabs. Reserved for AdvancedOverflowModule;
ignored until that module is present. Default: false.
Tab-header overflow behaviour. One shared block across the overflow axis:
