I have lost hours of work due to this bug. Set up a bulleted or numbered list and place a helpjuice callout nested within it. Then, within the helpjuice callout, create a list. The editor will look something like this: For Example: 1) Item one 2) Item two Helpjuice callout attached to item two - bullet 1 within the helpjuice callout - bullet 2 within the helpjuice callout 3) Item three Now this configuration looks fine within the new editor. What happens as you continue to work on the article is that the auto save will hang, and manual save or publish attempts will fail with the unsaved changes pop-up displaying in the browser. Eventually, if you tell your browser to "prevent additional dialog boxes" from helpjuice and click publish. All work prior to adding the nested helpjuice callout will be saved. Everything after it will be lost, and the helpjuice callout you added will be blank. To me, this isn't a unique use case either. We have an orderlist of steps to complete a process and use the helpjuice callouts as note callouts during these steps. occasionally its a multi-part note or two unrelated things to be aware of at that point in the steps.
