Research direction

Start by reviewing the referenced PR comment at https://github.com/eclipse theia/theia/pull/7847#issuecomment 634273331 for context. Then investigate icon rendering in Theia's Electron shell, focusing on how icons are loaded and displayed when running VS Code extensions. Look at source files in packages/electron or similar for icon handling. Since the issue lacks reproduction steps, attempt to create a minimal reproduction by testing with different icon formats or themes.
