TypeError when saving #503
Description
When saving a notebook using the Spyder menu, it looks like the notebook is not actually saved and the following message appears in the Internal Console:
Uncaught TypeError: Cannot read property 'dispatchEvent' of null
Saving the notebook using the Jupyter toolbar does work.
It looks like an error in our save function; possibly it can not find the save button because it changed name or id or class or something like that.
