This metadata has been changed to contain other information. Readers of information from 3MF need to adjust their stance too to filter out the information they need from the metadata of the metadata.
Contributes to issue CURA-7615.
This reverts commit 35d6aad6cd.
This is causing a very weird crash when autoslice is enabled:

The property exists all right. It's in the dir() of the CuraApplication instance. PyCharm's debug mode also gives a traceback when trying to evaluate the property. It clearly thinks it's there, but then it's not or something. Very weird. We need to take a better look at this than this quick fix.
We're getting some reports that people are suddenly logged out. The working
theory is that they are mixing staging & production builds. This logging
should tell us enough to find out if that is the case!
