When a file is placed on a page, e.g. via the "Files to download" block and the state saved to the timeline, it does not appear on the timeline once the file has been deleted from the Files area though it should still appear on the Timeline.
1. User A has a page with the "Image" block and the "Files to download" block. The download block contains both the image and also another file.
2. User A saves that state to the timeline.
3. User A deletes the image that is used in the "Image" block and the "Files to download" block from their file repository.
Expected result: The image is still displayed in the timeline.
Actual result: The image is not displayed in the timeline neither in the "Image" block nor the "Files to download" block thus not rendering it a true respresentation of the state of that page at that time.
A problem with this is if a user needs to delete content to free up space then no space will be made available as the content will continue to exist for versioning
