Designer stroke conical gradient isn't working properly following a flip

[Gear maker]

I rarely us a conical gradient in a stroke, so I don't know if this is something only in 1.10.3 or not.  Notice how in the 5:30 position there is an abrupt change in the color.  The shape of this "change" changes by zooming.

There is nothing in the drawing but this one ellipse.  The fill also has a conical gradient, but that doesn't seem to be causing the stroke's problem.  Moving the stroke's gradient handles at 2:30, 6:00, 11:30, 10:00 and 9:30 do not have any effect, but the handle at 12:30 does affect this change.  Actually the 2:30 handle does affect the issue if it's moved almost to the 6:00 position.

I tried recreating the entire ellipse and the problem did not show up. Then I found that doing a Flip Horizontal corrected the issue.  Also a Flip Vertical could reproduce the problem.  And I had done a flip horizontal in the original drawing.  It's apparently the flip that doesn't play well with the conical gradient on a stroke.

There is a dotted line on the Conical Gradient which indicates the ellipse has been altered somehow after the gradient was applied.

Double click on the dotted line's terminal handle and it will disappear, restoring the unaltered gradient. I changed the fill to solid orange.

Old Bruce, thank you.  I had not taken notice of the additional line.  Even though I know gradients do add this when copied.  That took care of it.
