We are also experiencing this precise issue on a frequent basis. It is easily reproducible. We are also experiencing this problem when folks open existing documents and then attempt to edit properties. The issue seems to be occurring more often lately.
Specifically, we used to be able to create a new document, and if we clicked the library link in the breadcrumb at the top of Word Online (instead of clicking back in the browser, or closing a new tab) it would not lock the file for property editing. Now it is locking the file even in this case.
Is it Microsoft's position that creating a new document in a SharePoint document library using an Office Online app is not recommended or supported?
More likely this is a growing bug that needs to be escalated and addressed ASAP. This is a huge problem for user adoption, and for, well, USE.
