Markers / Arrow Heads don't use stroke gradient

Summary:

Markers like arrow heads take on the stroke colour, but when the stroke colour is a gradient, it doesn't function correctly.

Steps to reproduce:

  • open Inkscape
  • make a single line with two arrowhead markers (one on each end)
  • Assign a gradient to the stroke

What happened?

The arrow heads seem to take one colour stop from the gradient, and ignore the other side. Even worse, if you then rotate the line around the colour changes to the opposite stop (in the case of the test, they vanish because of the 0 alpha on that end of the gradient)

What should have happened?

Arrowheads should use the same gradient as the stroke.
