[YMTC]: Is robot debris still part of the robot?

[Basel A]

First, let me say that this is a purely hypothetical situation.

Let's say a robot scales, but before the matches ends, a piece of their bumper completely falls off. The rest of their bumper is above the low goal, but the piece that fell off obviously is not. Per the rules, the robot is disabled, but they hold the elevated position. Is this a valid scale?
