S-tooltip not working on s-chip element, intentional?

Is there any reason, why the s-tooltip feature does not function when connected to an s-chip element? It works with s-clickable-chip, albeit with a small caveat of only displaying when hovering directly on the text of the s-clickable-chip. But s-tooltip does not work at all with s-chip.
