Document is not editable with Semantics enabled

[estevez-dev]

Steps to Reproduce

1. Enable Semantics on the app start by adding to the void main():

WidgetsFlutterBinding.ensureInitialized();

SemanticsBinding.instance.ensureSemantics();

2. Try to edit the text in FleatherEditor

Environment

• OS: MacOS Flutter web
• Flutter version: 3.27.2
• Fleather version: 1.20.1

Logs

No any logs

Wrapping Fleather widgets in ExcludeSemantic doesn't resolve the issue.
