Problem using the SuperEditor with a TabBar

[hillelcoren]

When adding the editor to a TabBarView once the screen is filled with text the TabBarView automatically changes to the next tab rather than scroll down in the editor.

A related problem is when the editor is used on mobile in a TabBarView if the keyboard is shown it causes the tab bar to change to the previous tab.

Here's a simple example:

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        bottom: TabBar(
          controller: _controller,
          tabs: [
            Tab(
              text: 'Tab 1',
            ),
            Tab(
              text: 'Tab 2',
            ),
          ],
        ),
      ),
      body: TabBarView(
        controller: _controller,
        children: [
          ExampleEditor(),
          ExampleEditor(),
        ],
      ),
    );

@hillelcoren can you provide a video of these two bugs in action? I'm not entirely sure what you're describing.

I've retested using the editor in tabs, I'm no longer able to reproduce the issue above but I'm seeing this error in the console.

@hillelcoren is that problem caused by the widget tree you originally posted? Does it happen immediately upon loading the UI?

[hillelcoren]

Yes, this is trigged by the widget tree above.

The error occurs when I type into the super editor enough lines of text to get to the bottom of the screen.
