// DRAGON WARNING!!! DO NOT TOUCH THIS IF YOU DON'T KNOW.
// TL;DR: Always update "container_id" first!
//
// Other widgets such as MaterialsView have bindings towards "materialProperties" and its properties. Here the
// properties are updated one by one, and each change can trigger a reaction on those widgets that have
// connections to the property gets changed, and some reactions will use functions such as
// ContainerManager.getContainerMetaDataEntry() to fetch data using the "container_id" as the reference.
// We need to change "container_id" first so any underlying triggers will use the correct "container_id" to
// fetch data. Or, for example, if we change GUID first, which triggered the weight widget to fetch weight
// before we can update "container_id", so it will fetch weight with the wrong (old) "container_id".
