Message preview cannot expand/collapse after upgrade 3.5+

[cobolbaby]

Description:

After upgrading to the latest version, the message preview section can no longer be expanded or collapsed.

Previously, clicking on the preview area (or the expand/collapse button) would toggle the full message content correctly. However, after the upgrade, the preview remains fixed and does not respond to user interaction.

Environment:

• Version: v3.5.3
• Browser (if applicable): Chrome
• Deployment type: Docker

Steps to Reproduce:

1. Upgrade from version 3.2.x to 3.5.x
2. Open the message list page
3. Click on a message preview
4. Try to expand or collapse the preview

Expected Behavior:

Message preview should expand and collapse normally when clicked.

Actual Behavior:

Clicking does not trigger expand/collapse. No visible response.

Ha thanks @cobolbaby - I knew something was looking different with the lines in the editor but I couldn't figure out what it was! We'll look into it.

The issue still persists after upgrading to version 3.7.2.
