Weird Stair Stuff - part 5 - Top Riser Line Missing

Following on from my post about Revit Stair Subcategory Visibility, I noticed another strange anomaly with stairs in plan.
If you have a stair that ends with a riser and has projecting nosings, the very top riser line of your stair will not display in plan.

Run type properties for tread and riser
Run instance properties

Top tread / riser in section

Instead of showing the top riser and nosing lines, Revit will display an 'Outline' line - this represents the actual top nosing line, or where it would be if your run ended in a tread.

End With Tread

If your stair run does actually need to end with a tread, then the subcategory visibility graphics presents you with a different problem:

Run ends with a tread


It displays correctly in section but then you have a top tread that may or may not be the same material as the floor finish - and you get a joint line between the floor and the top tread.  If they are the same material you probably don't want to see the joint line;  if they are different materials you may want to see the joint at detailed views but not in general arrangement views. 
Run ends with a tread
It cannot be controlled by subcategory because you would lose all the outlines (including sides of stair) if you turn off the 'Outlines' subcategory.  So you would need to resort to the 'Linework' tool to hide the line.

The factory has at least corrected the problem of where the stair path arrow ends - on the top riser/nosing line.  With the old stairs it used to include the top tread, which ws totally confusing.
