/**
 * Plan is to store the object-mode per workspace, not per object anymore.
 * However, there's quite some work to be done for that, so for now, there is just a basic
 * implementation of an object <-> workspace object-mode syncing for testing, with some known
 * problems. Main problem being that the modes can get out of sync when changing object selection.
 * Would require a pile of temporary changes to always sync modes when changing selection. So just
 * leaving this here for some testing until object-mode is really a workspace level setting.
