Unable to use custom block types in TextEditorField

[jahudka]

Given the following field:

yield TextEditorField::new('content')
    ->setTrixEditorConfig([
        'blockAttributes' => [
            'default' => ['tagName' => 'p'],
            'heading1' => ['tagName' => 'h2'],
        ], 
    ]);

When editing an existing entity the configured block attributes aren't respected - all <p> and <h2> tags in the editor are converted to <div>.

This happens with EasyAdmin v4.3.4. Looks like the cause is the Trix editor itself (see here) - and from what I'm seeing I'd suggest the best possible fix for this issue would be to abandon Trix in favour of something sane and mature.
