Improve selection rendering

Do you think that this gif creates the right mental model of how the engine behaves?

To me it looks like the selection which is rendered before applying bold is significantly different than the one rendered after that. Which is not true – it's exactly the same selection with the same properties.

That's why I don't think that the selection should be displayed as if was placed before text nodes.

I'm not sure if this will work but I'd like to see a prototype of something like:

For me this ticket is very important because the role of the inspector will be much more significant in creating a mental model of CKEditor 5's internals than everything we'll ever write in the documentation.

That's a nice idea, we'd need to make sure it's understandable for devs without additional docs. Something like a tooltip on hover would be sufficient.
