No Z-Hop for Gap Fill in Top Infill

[rynbrd]

Describe the bug
No z-hop is present to or from the gap fill in solid infill even though a retraction is present prior to the travel moves. This causes nozzle scarring since the travel moves happen across already printed solid infill.

Here you can see the fill happening in a curved corner of solid infill:

You can see the travel move coming to the gap fill did not have a z-hop.

Here you can see the retraction and travel move leaving the gap fill:

To Reproduce
Steps to reproduce the behavior:

1. Enable retractions. I have configured firmware retractions in Klipper and enabled "Use Firmware Retractions" in SuperSlicer.
2. Enable z-hop. I have configured 0.4mm z-hops and selected "Only on Top".
3. Ensure retractions are enabled where possible. I have enable "Retract on Layer Change" and disabled "Only Retract when Crossing Perimeters".
4. Configure "Monotonic (filled)" for the infill.
5. Slice a part which requires gap fill on the top surface and has a travel move afterwards.

Expected behavior
I expect to see a z-hop on the travel before and after the gap fill.

mmm... "only on top" means "only on extrusions marked as top solid infill" and it seems like the gapfill from the fill isn't taggued correctly in that regard.

This is fixed for me using 2.3.56.5.
