When a confluence page is left open in one tab in edit mode over a few days the users presence is duplicated.

Issue Summary

If a user leaves a page in Confluence in edit mode overnight or for a few days then it appears that this same user is editing the page multiple times, i.e. their avatar is listed many times even though they only have it open once.

Steps to Reproduce

1. Open a page and edit
2. Leave in edit mode overnight
3. Check tab

Expected Results

The page to show only ONE session against the user who has it open.

Actual Results

The page shows more than one edit session despite that only one browser tab is open

Workaround

Close or publish the page and when the page is reopened the sessions will have cleared.
