Periapsis above the atmosphere on Duna, spacecraft "on a suborbital trajectory"

[Kerano]

KSP 0.90.0, no mods.

Spacecraft orbiting Duna are registered as "on a suborbital trajectory" when the periapsis is above the atmosphere but below about 50-60 km. Contracts requiring an orbital station are not fulfilled until you raise the periapsis to above this level.

I believe there is a similar issue with Jool, when the periapsis is below about 200 km.

Probably the same bug that Jool has, where the atmosphere height variable has the wrong value in the place it looks to determine whether or not it's orbital or sub-orbital.

Check the bug system to see that it's registered.

Same thing on Kerbin as well, the atmosphere runs out at around 69200 metres, but only counts as orbital above 70000.
