Tab width in 'shaped' bar style

Hi,

I'm using the style 'shaped' for all my frames (floating and
non-floating), i.e.:

de.defstyle("*", {
	bar = "shaped",
}),

However, the tab width depends on the maximum tab width in their
containing frame. Is there any way for the individual tabs to only
stretch as far as their own title width?

Kind regards,
