3D printer brand / version + firmware version (if known)

Ender 3 (Marlin 2.0)

Behavior

When raft is enabled, the layer above the raft is not considered an initial layer - the raft is considered an initial layer instead.

This causes most of the ABS and PETG prints to fail due to the high speed of printing since there's no control for the speed 2nd layer .

Expected Behavior

PrusaSlicer should not consider the raft an initial layer, the initial layer should be the actual first layer above the raft.

I think that current behavior is correct. From my point of view, the first layer is the one that has no plastic below. I always thought that the reason some parameters are separated for the first layer is because printing on bed differs from printing on plastic. If your object does not print on raft because of too high speed, I'd consider lowering the overall speed or use layer range modifier.
I think we should close the issue unless someone comes with a different opinion.

Fixed with b29c0ea
Implemented configurable speed and acceleration settings for the first
object layer over raft interface:
"first_layer_speed_over_raft", "first_layer_acceleration_over_raft".
Fixes I have a question about the speed of the first layer after the raft. #6623
Fixes Layer After Raft Is Not Considered First Layer! #6166

The fix will be released with PrusaSlicer 2.4.0-alpha1.
