Bridge counterbore holes not working properly

Im looking for a solution to print counterbore holes properly. I found the Bridge counterbore holes setting, and set it to Partially bridged. That didn’t work, actually the result is empty. Looks like a bug, but could be i misunderstood the setting.

I compared the setting with Orca slicer, where it works. Also setting it to different setting looks like it is working.

OpenSCAD test file:

$fn=100;
difference()
{
    translate([-10, -10, 0])
    cube([20, 20, 10]);

    cylinder(d=8, h=5);
    cylinder(d=3, h=11);
}

export to STL and imported it into bambu studio (orient big hole to plate). Set it to standard 0.20mm setting. Only changing the Bridge counterbore holes = Partially bridged.

I would expect layer 26 to have some bridges above the hole, but it is empty at layer 26 above the hole. I checked with other settings and with Orca slicer, and there it works as expected.

Result it Bambu Studio:

Result in Orca Slicer:

Where is this bridge feature? Did it just get put in??

To be honest, i don’t know if it is new. I’m running windows Bambu Studio V 2.8.1.55 (Beta).

[update] I checked the release notes:
It is introduced end of June in V2.8.0 also a beta. Not in a public release yet.

It is under the Quality Tab, in the Advance section.
