ID of cylinder smaller where intersected by side hole. Looks like the X-Y hole adjustment amount. Only does it with XY Hole Compensation turned ON. #1462

Is there an existing issue for this problem?

Printer

Ender3V2, Ender3 Pro, both Klipper. Both do it as commanded.

How to reproduce

Create a cylinder and put a hole in the side. I put a vertical bore (25-30mm) down it and a 5mm hole in the side. Wall thickness does not mater.
Shows smooth when brought into the slicer.
Slice it - I tried scarf on/off, accurate walls on/off, Detect overhanging walls on/off. It puts extra material in the bore I.D. where the hole is located.
Just had a thought about X-Y Hole compensation - yep - does it by the amount of hole compensation that is applied.
X-Y Hole is not applied in the section that has a hole intersecting from the side. This renders X-Y hole not usable as an adjustment that can be changed for different nozzles, for instance. Make X-Y hole 0.6 and it'll be very obvious!

Actual results

The cylinder bore is not interpreted as a vertical hole when intersected by another shape from the side.
There is extra material in the vertical section cut by the hole on the side. Cura does the same thing when X-Y hole is >0. Picture was with it off.
This causes the bore to be too small and the parts do not fit. It should be smooth, as shown in the first picture. Love that beautiful Z-seam!

Expected results

Expect a smooth bore with a hole in the side.
