How to reproduce

Open attached project file and slice.

What should slice as a top layer is sliced as a bridge layer. ~~To work around the issue I change the indent to be one layer lower or one layer higher.~~ It seems to be related with that layer sharing the same layer as a bridging layer after the infill. AKA first top layer.

To add, I have also tried this on 1.9.0 with the same results.

Edit: I want to amend my initial workaround. It appears there is still an issue where a bridging layer is added even thought is not needed. Even with the indent being only .6 mm from the surface. Orca slicer still puts a bridging layer right before the top layer. Layer 27: 2024-01-21_11-12

Layer 29: 2024-01-21_11-12_2

I seem to be running into this issue as well. Initially I had the issue with a 0.6mm indent and found that a 1mm indent worked as expected. Upon further testing a 0.9mm indent it just completely fails to do a top surface at all for the indent.

Below are my 3mf and log files as well as screenshots showcasing the behaviors.
