Issue Summary

Page content where 0-width spaces is present breaks the comparison logic

This is reproducible on Data Center: NA

Steps to Reproduce

Please note : Steps to reproduce in UI is still unclear because Confluence does not support 0-width space from UI but during investigation of version compare, this can be reproduced using update API i.e

PUT /rest/api/content/<contentId>

1. Pick the version where you see logic is broken.
2. Get the storage format of the two versions

rest/api/content/<contentId>?expand=body.storage&version=number

3. compare the two version storage format ( you can use visual code)
4. You should see the space appended in successor version

Expected Results

The version compare should work as usual

Actual Results

It breaks the version compare logic

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
