Description
Currently if you clip a mark, the tip doesn't get clipped and you might end up with surprising results when using facets.
For example the tip shown below, belongs to the facet highlighted in red.
(The cause in this case is that the y scale's domain is set to [0, 0.09] and the excess area between 9% and 100% is clipped out.)

Research direction
Start by reproducing the faceted example with the y-scale domain set to [0, 0.09], using the attached image as the expected context. Trace how the clipped mark and its tip are rendered. Done means the tip is clipped consistently with its mark, including when facets are used.
