Description
I’m encountering a persistent error in Home Assistant 2025.3.4 related to the LG WebOS Remote Control custom card. The error appears multiple times daily in the logs:
Logger: frontend.js.modern.202503060
Source: components/system_log/__init__.py:331
First occurred: 13:00:13 (5 occurrences)

Uncaught error from WebKit 605.1.15 on iOS 18.4.1
Error: Failed to execute 'define' on 'CustomElementRegistry': the name "lg-remote-control-editor" has already been used with this registry
at /hacsfiles/LG-WebOS-Remote-Control/lg-remote-control.js:30:106
at t (/hacsfiles/LG-WebOS-Remote-Control/lg-remote-control.js:1:251)
at module code (/hacsfiles/LG-WebOS-Remote-Control/lg-remote-control.js:272:28)
Steps to Reproduce:
1. Install the LG WebOS Remote Control card via HACS.
2. Add the card to a Lovelace dashboard.
3. Observe the Home Assistant logs for the error. 
Expected Behavior:
The custom element lg-remote-control-editor should be defined only once to prevent the error.
Actual Behavior:
The error indicates that lg-remote-control-editor is being defined multiple times, leading to the Failed to execute 'define' on 'CustomElementRegistry' message.
Environment:
• Home Assistant Version: 2025.3.4
• LG WebOS Remote Control Version: Latest via HACS
• Browser: Safari on iOS 18.4.1 
Additional Information:
This issue has been previously reported in the community, with users experiencing similar errors when multiple LG TVs are present in the network. 
Suggested Fix:
Implement a check before defining the custom element to ensure it hasn’t been defined already:
if (!customElements.get('lg-remote-control-editor')) {
customElements.define('lg-remote-control-editor', LgRemoteControlEditor);
}
This approach would prevent the error by ensuring the custom element is only defined once.
