The inconsistency is a direct consequence of #100493 : the operator does not take in account which channel is selected for all non-grease-pencil-layer keyframes.

Thing is, the 'jump to next/previous' keyframe operator is invoked from the viewport, and not the dopesheet, so there is actually no (easy) way to know which dopesheet is open. You could have both main and gpencil dopesheet opened in your workspace, or no dopesheet at all, for that matter. I don't think the behavior of the operator should depend on that.

One fix for this could be to say that the operator will only use selected animation channel if the active object is a grease pencil one. That may add even more inconsistency in the behavior of the operator though.

I see now that the operator can be called from the dopesheet as well, as you did in the video. So we can change this behavior when the jump is called from the specific grease pencil dopesheet. It would be inconsistent to the calls made from the viewport, though, is that a problem ?
