Expand Stroke Error

[Pšenda]

Expand Stroke does not work correctly, if the curve nodes overlap and their handles have the same direction and length.
This curve Expand fine:
 

Move node to overlap end node, handle isn't identical, Expand work fine:
 

Adjust handle of the node to identical direction, but not to identical lenghts, Expand work fine:
 

Adjust handle of the left node to identical direction and lenght, Expand don't create round cap:
 

Adjust handle of the right node to identical direction and lenght, Expand don't create round cap:
 

Adjust handle of the both node to identical direction and lenght, Expand don't create round cap:

Same on Mac.

@Pšenda For some reason I'm not getting the same results but I may be missing something in the workflow. Could you do a short screen recording from drawing the curve to adjusting the node handles and expanding.
