Description
Describe the bug
In the micro:bit offline app, the Advanced category in the Toolbox displays a left color indicator bar with an incorrect width. The bar appears noticeably wider than other category indicators, causing visual misalignment in the Toolbox UI.
Steps to reproduce the behavior:
- Download and open the micro:bit offline app: https://makecode.microbit.org/offline-app?version=v8.0.19
- Create a new project.
- In the Toolbox, expand the Advanced category.
- Observe the left color indicator bar next to the category label.
Actual behavior
The Advanced category’s left color indicator bar displays with an abnormally large width, misaligned with the rest of the menu items.
Expected behavior
The Advanced category’s left color indicator bar should keep a consistent standard width as other Toolbox categories.
