Update attributes when non-editable

[Winexcel]

I wrote my own spoiler extension, it works like a charm, but when I set my editor to non-editable, my spoiler doesn't work, button which update "show" attribute doesn't work.

I set editor to non-editable mode like this:
this.editor.setEditable(false);

My spoiler works very easy, I just update "show" attribute when click by the button.

Is it possible to update attributes and react to DOM events in non-editable mode?

I add a github repo for this problem, i solved this by replacing show attribute, i just duplicate show in my component and toogle this data property, but i also dispatch this property to tiptap. https://github.com/Winexcel/tiptap-spoiler

I think this approach might be bad, therefore i need some feedback from core team about this problem.

And another problem which i have with this approach - i can't nest one spoiler to another, i don't know why it doesn't work, but if i set content with nested spoilers - it works! Magic!)

Why i can't add spoiler into another from commands?

As discussed in #1239 I also removed the editable check in updateAttributes.
