Description

After upgrading the project from version 614 to 655, button styles are no longer being rendered correctly.

Before the upgrade everything worked as expected. After the update, the buttons appear without their styles, while the rest of the application seems to function normally.

There are no visible errors in the console and other UI components appear to be unaffected. The issue seems to be limited specifically to button styling.

Please provide the exception or error you saw
