The issue was that the struct `tPoseSlideOp` tracks the viewport overlay flags so they can be restored after the operator has run. But the flag was stored at the end of `pose_slide_invoke_common` which exits early if no keys are selected. This then calls `pose_slide_exit` which sets the viewport flags to 0, because they were never stored in the first place. The fix is to move the storing of the flag up to `pose_slide_init` to ensure that it is captured as soon as the struct is allocated.
