Rich editor timeout notification remains after the editor successfully loads

This issue respects the following points:

• I have searched for existing issues
• The issue affects the Notes Android app, neither the Notes server app nor the Nextcloud Android app.

Describe the bug

Describe the bug

When opening a note in rich editing mode over a slow connection, Notes shows a message saying that loading takes longer than expected and offers switching to plain editing.

If I wait, the rich editor eventually loads successfully, but the warning remains visible for the entire editing session.

Steps to reproduce

1. Use a slow or unstable mobile connection.
2. Open a note in rich editing mode.
3. Wait until the loading warning appears.
4. Continue waiting without switching to plain editing.
5. The rich editor loads, but the warning is not dismissed.

Expected behavior

The warning should be dismissed automatically when the rich editor reports that loading has completed.

Stacktrace

No response

Start by tracing the rich editor loading flow and the timeout warning shown during slow connections. Reproduce the issue with a delayed load, then verify that the warning disappears when the rich editor reports successful completion and remains available if the user switches to plain editing.
