Broke down in the secret passage

[SoccerTaco]

It seems like it is possible for a robot to become inoperable in their opponent's secret passage, next to the brattice, such that they are blocking their opponent from acquiring more boulders.

I've been wondering what would happen in this situation. If blue robot is broken down, red robot can come in and try to get to the brattice, contact the blue robot and a tech foul will be assessed to blue. But, then what? Red can back up and hit blue over and over, trying to get push them out of the way. Initially, that might be tech foul after tech foul assessed to blue. But at some point, when the futility of moving blue out of the way is apparent, would that start to become a violation of G11 on red?
