We have a page that has a Draw.io drawing as part of its content.
We then included that page from another Space, and noticed immediately that the very first version of the drawing was showing up on the page that referenced the original one.
An interesting observation, is that there seems to be some offset going on here, since we tested pressing "Save" on the Draw.io editor a few times on the original page, and we could then see that on the included page, the drawing started to progress through the version.
So every press of "Save" on the original page, bumped the version on the included page by one, so we could actually see it "go through" the old versions of the drawing.
This might be related to this question, seeing as how the last commenter in that question seems to have the exact same problem as us.
Any known workarounds or fixes? (Except having to press "Save" a bunch of extra times on the original page...)
