Persistent Loading Indicator Issue in Outlook WebAdd-in After Full Initialization

I have developed an Outlook web add-in using TypeScript, managed by Webpack. While the add-in functionality works as expected, I am facing an issue with a loading indicator that never disappears, even after the add-in has fully initialized.

I have tried the following steps to resolve this issue:

Ensured Initialization: Used Office.Initialize along with Office.Ready to confirm that the add-in is fully initialized.

Parent Communication: Passed the initialize event to the parent to ensure it recognizes that the add-in has been loaded and initialized.

Configuration Checks: Tested various configurations, including different polyfills and tsconfig settings, to identify any potential causes.

Despite these efforts, the loading indicator persists, even when the add-in fails to load entirely.The "Loading..." progress bar remains active indefinitely, suggesting that there might be an issue with how the initialization state is being communicated or processed.

Has anyone experienced a similar problem, or could you provide guidance on how to resolve this persistent loading indicator issue in Outlook Web Add-ins? Any help or suggestions would be greatly appreciated
