Text near hyperlinks incorrectly gets converted into a hyperlink after edit

Summary

After upgrading Confluence, editing certain pages can cause hyperlink formatting to be applied to text that precedes a real hyperlink. This only occurs when editing a page for the first time after an upgrade with Synchrony enabled.

Steps to Reproduce

1. Install Confluence 5.10.8
2. Create a page
3. Use the source editor to edit the page with storage_format.txt
4. Save the page
5. Upgrade Confluence to 6.7.2
6. Edit the page

Expected Results

The page renders as it did in 5.10.8

Actual Results

Text formatting is changed to that of a hyperlink

Notes

• This only affects pages that existed BEFORE the upgrade. If you use the source editor to add the storage format after upgrade it does not replicate the issue.
• Reverting to the pre-edit version also does not allow you to replicate the issue. This will affect any page only once.

Solution

Use the built in formatting tools to change the text formatting.
