Gui of container does not update immediately when CustomName is changed

If the GUI of a container is open, and data merge changes the CustomName of the container, the displayed name does not update until the user closes and re-opens the container.

For example, data merge block 694 66 562 {CustomName:'{"text":"example"}'} will not update the gui until it is re-opened
