Issue Summary

When the users are pasting links with encoded URL in Confluence Team Calendar events,  they are Double-encoded causing the links to break 
 

https://abcde.atlassian.net/lets-train/event_view.php?id%3D1234%26caller%3D

The destination page does not load as expected due to the broken parameters.

Steps to Reproduce

1. Go to a Confluence space and open the Team Calendar.
2. Create a new event (or edit an existing one).
3. In the Description or Location field, paste a URL that contains encoded parameters.
   Example: https://abcde.atlassian.net/lets-train/event_view.php?id%3D1234%26caller%3D
4. Save the event.
5. Click the link in the event or copy it to the browser address bar.

Expected Results

• The link should work as originally intended, with the encoded parameters preserved (e.g., %3D for =, %26 for &).
• The destination page should load correctly.

Actual Results

• The % characters in the encoded parameters are further encoded to %25, resulting in double-encoding (e.g., %3D becomes %253D).

Workaround

Please use a decoded link for now.
Or paste the link in where section
