Why do all Blocks get initialized twice? When you initiate the editor with readOnly true, i've got a problem with custom block tool

I created a custom Block via https://editorjs.io/tools-api/.

I am creating the Editorjs with readOnly true, and when i output the data from my Tool constructor, it will get initialized twice with different readOnly values.

```
constructor({ data, config, api, readOnly, block }) {
console.log('readOnly', readOnly);
}
// readOnly false
// readOnly true
```

Expected behavior: Just initialize every block once?

That means i need to change my custom block tool, so it handles the "switch" from edit to readOnly... But i don't really need a toggle. i just want to show the content in read-only mode.
