detailed route spends 30 iteration on fixing trivial pin access.

Describe the bug

Fallout from https://github.com/The-OpenROAD-Project/OpenROAD/issues/5300

All but V1 cut spacing violations were solved after the 4th iteration.

It took detailed routing 30 iterations to put all V1 on the metal1/metal2 track intersection. Why aren't the via placed at this violation free location to start with ?

Is this an issue with pin access computation ?

Expected Behavior

Put V1 on violation free metal1/metal2 track intersection.
