Gradient stops not working correctly if the gradient is used as path stroke color

[RedFurryDemon]

Bug occurs inconsistently. Further testing needed.

Expected behavior:

Like gradients used for any fill colors or stroke colors of shapes other than path, gradients used as path stroke colors should update both in the preview window and in the SVG text editor immediately after any of their stop properties are changed.

Current behavior:

Gradients used as path stroke colors may fail to update in the preview window until the preview is zoomed in/out. They may also fail to update at all in the SVG text editor. These problems seem to occur together.

Sample file:

(Steps to reproduce): Using GodSVG UI, edit any of the stop properties of g_stroke. The bug may or may not appear.
