I hear ya. But to be honest, what they are doing here is fine, and doesn’t seem malicious. There is an Open Document specification and they stick to it, but the spec doesn’t enforce everything. For instance for the ordering of certain elements on the page, I bet you they store store those elements in memory in an efficient data structure where ordering doesn’t matter, so when writing out the memory to disk, the easiest for them to do is just write it out in what order it appears in their data structure.

But there are probably other cases where they are not so innocent.
