Ossia doesn't affect bar number distance alignment?

I have an ossia at the bottom staff and already activated this:


Now I get this result:

But I want the bar numbers to be aligned across the system, I already activated this option as well:


Is there a way to align the bar numbers here?

Furthermore: Is it intended that m. 4 is also moved? I see no particular reason for it

The bar number in bar 4 will be moved because Dorico is determining which staff the bar number is positioned relative to according to the rhythmic position of the start of the bar rather than where visually the bar number is drawn.

Dorico’s doing the best it can inasmuch as it’s aligning the bar numbers that are drawn relative to each staff, but because you have the bar numbers changing which staff they are relative to, this is what you get at present.
