This fixes the crash by removing the `do_view3d_header_buttons` handler. The code can work at a higher level here, using the operator for setting the select mode, which makes this patch a cleanup as well. The operator now has a description callback to add the custom description used for the behavior in its invoke method. Differential Revision: https://developer.blender.org/D13660
