What happened?

1. Description of the Problem:
The Transparent Panels extension fails to apply transparency to all panels as expected. Instead, the transparency effect is only visible on a single panel located on the secondary monitor. All panels on the primary monitor remain completely opaque, regardless of the extension's settings.

2. Steps to Reproduce:

1. Install and enable the "Transparent Panels" extension by germanfr.
2. Ensure a multi-monitor setup is active (e.g., primary and secondary monitors).
3. Configure the extension settings to enable transparency (e.g., set opacity to a value below 100%).
4. Observe the panels on both monitors.

Expected Result:
All panels on both monitors should display the configured level of transparency.

Actual Result:
Only one panel (on the secondary monitor) becomes transparent. Panels on the primary monitor show no transparency effect and remain solid.

3. Additional Information:

• The issue persists after restarting Cinnamon (Ctrl + Alt + Esc).
• Disabling and re-enabling the extension does not resolve the problem.
• The problem occurs with default panel configurations and custom panel layouts.
• No error messages are visible in the System Log or .xsession-errors.
• The issue is consistent across reboots.

4. Workaround:
None currently identified. Manually adjusting panel transparency via the Themes settings does not provide the same dynamic control as the extension.

5. Potential Cause:
The extension may incorrectly identify monitor priorities or panel instances, applying the effect only to the last panel created or to a panel on a non-primary monitor due to a bug in the panel enumeration logic.

6. Request:
Please investigate and update the extension to ensure transparency settings are applied consistently to all panels across all connected monitors.r
