Add sanity check to avoid potential crash in the Collabora Online server

Make sure some coordinates don't become huge negative numbers. This
doesn't fix the unknown root cause of course.

I could not actually reproduce the crash with a server based on this
branch, though. There already was such a sanity check here in this
branch, but for Android only. I now made it cross-platform.

Let's use the same Change-Id as in the corresponding commit in the
co-2021 branch.
