When using any of the operators in `graph_slider_ops.cc` and cancelling the operation, the location of the object in the 3D viewport might get stuck in the state prior to cancelling. To fix this, explicitly update the depsgraph when cancelling. I've only done that in case of cancelling, since that's where the issue came from. For fear of introducing performance regressions I'm not tagging the depsgraph for an update at any other point. (It might already do that at some other part of the operator code though) Pull Request: https://projects.blender.org/blender/blender/pulls/115810
