How to reproduce

1.Add a modifier so that it intersects with a bridge (e.g., a cubic modifier that changes infill).

Run slicing.

Actual results

One side of the bridge hangs in the air at the modifier boundary (without any support). Then another bridge is printed, which should have been anchored to the previous one, but isn’t.

Expected results

The bridge should be generated so that its ends are properly anchored, not left hanging in the air.
