UI/UX Game wrongly indicating 0 DeltaV for any stage that does not contain the original root part

Expected delta-v to show for a separated vehicle but it showed 0 delta v

Steps to replicate (what that I did):

1. Create a vehicle on another vehicle which separates via a decouple (eg. a probe which separates from a larger craft. Note: construct probe on larger craft, not as its own craft and then attach)

2. Separate sub craft.

Adding a stage to the bottom of the staging tree and moving the active engine in there brings the DV back. Perhaps this helps in fixing the issue.

This is a pretty severe bug as, thanks to the unholy decision to prevent maneuver nodes to be created when here's "no fuel," it means you can't get home from other planets once this happens.

After docking, vessel indicates no delta V available. Has fuel and appears to operate in spite of no delta V. Engine ignites and burns, but results in no change in orbital speed or fuel reduction. Orbital info does not change.

Detaching a craft off the main craft (so the detached craft does not contain the rot part) results in the craft reading 0 on the dv readout.

Persists through quickloads.

Annoying for landing boosters.
