Engine().brakethrust does not account for inertia dampeners

[tangowrangler]

I am working on a mod that attempts to implement autopilot functionality to the player controlled ship. For that i need to estimate the brakethrust of my vessel to plan good maneuvers. The only place the AI uses this variable is in dock.lua which maybe a a real bug. Look at the screenies below for details.

 

No brakethrust with the whole ship being an inertia dampener

 

Brakethrust shows up with directional thrusters
