See the attached test case.

Chrome renders it correctly, Webkit does not. The last two lines should be almost identical. One has stroke-dasharray="0.001,1.999" while the other has stroke-dasharray="0,2". Webkit is treating the latter as if it were "1,1".

Release 140 (Safari 15.4, WebKit 16614.1.1.5)

This is a bug in an underlying graphics framework, and will be tracked by the above radar.

We believe the fix for this is available in macOS Ventura Beta 1 (and newer).
