Engine shutdown when passing invertRotAltitudeThreshold

[Kerbinator-Fras]

When you pass invertRotAltitudeThreshold (originally written at 145000m for Earth), engine will suddenly be off.
I'm currently playing it for my (unofficial) customized RSSRO, and this will waste 1 ignition.

Anyway, use persistent thrust might help a little bit (given that RO ignitions being precious.
