DRT creates redundant arc net when connecting to reconfigurable cell
Describe the bug
The cell is reconfigurable. Its base layers are the same and the function can be changed with different metal2 connections.
Interesting area are show in orange.
DRT tries to connect to the Q pins of the cell:
Since the Q pins are connected together in the cell with metal2, DRT connects to the metal2 shape
But the router create a useless arc wich causes a min hole violation.
This happens often. I have around 100 violations like this in my desgin.
I can try to make a testcase if needed.
Expected Behavior
No redundant arc
Environment

I reproduce the issue in a test case:
If we remove "-droute_end_iter 0" there is no violations but we can still se the redundant arc.
@osamahammad21 Why closing this issue without any explanation? A test case is provided.
