╡ EXCEPTION CAUGHT BY FOUNDATION LIBRARY ╞════════════════════════════════════════════════════════
The following assertion was thrown while dispatching notifications for QuillController:
Looking up a deactivated widget's ancestor is unsafe.
At this point the state of the widget's element tree is no longer stable.
To safely refer to a widget's ancestor in its dispose() method, save a reference to the ancestor by
calling dependOnInheritedWidgetOfExactType() in the widget's didChangeDependencies() method.

[EchoEllet]

Will fix this issue ASAP. For now, it has been disabled in #2221

[EchoEllet]

It seems that even after disabling/reverting #2009, returns false in clipboardPaste and disable pasteText.

And also pass false to pasteEnabled.

The text still gets pasted as plain text after using the paste hotkey (ctrl/cmd + v) on the web, this is not the case for desktop or mobile.

If anyone has any ideas or thoughts on where this paste is triggered, feel free to share them.
