App crashed due to null CircularProgressIndicator in `CodeEditorPane.setLoading()`

[euptron]

Problem Description

The app encounters a NullPointerException when attempting to access the CircularProgressIndicator (referenced as progressbar) in the CodeEditorPane.setLoading() method. This error occurs because the progressbar is not properly initialized in the LayoutCodeEditorBinding. When the app tries to update the progress indicator while reading a file, it crashes due to the null reference.

Steps to Reproduce the Behavior

1. Open the app and navigate to the CodeEditorPane.
2. Trigger an action that involves loading a file (e.g., reading a file with charset).
3. The app crashes when trying to update the progress indicator.

Expected Behavior

• The app should check the undo state in the CodeEditorPane without crashing. It should ensure that the ContextualCodeEditor object is not null before calling the canUndo() method.
