Describe the bug

Position the Editor's cursor at the start of its text area. Type some text inside an empty Editor and press the Backspace key. The text is not deleted.

If you use the cursor keys or click to reposition the cursor, the Delete and Backspace keys start to work.

To Reproduce

1. Open https://codesandbox.io/s/seb4r5
2. Position the cursor at the start of the Editor (before the word "The")
3. Press the Delete key - instead of text to the right being deleted, nothing happens
4. Type some text before the existing content in the Editor
5. Press the Backspace key - instead of text to the left being deleted, nothing happens

Expected behavior

The Backspace and Delete buttons should work in all Editor scenarios where the text editing is not prevented

Describe the bug

In a Native Editor scenario, if you open the View HTML window, the window can be closed only using the two buttons at its bottom.

To Reproduce

1. Open this StackBlitz example.
2. Click on the View HTML button.
3. Try to close the window using the "x" button in the upper right corner.

Expected behavior
The popup window should be closed when the "x" button is clicked

Describe the bug
The following JS error appears in the console when using the Insert Table tool of the Native Editor without choosing a table size to insert.

To Reproduce

1. Open this StackBlitz example
2. Click on the "Insert table" tool to open a popup
3. Click outside the popup

Expected behavior
No JS should appear when the user opens the popup of the "Insert Table" tool and doesn't select a table size in it.

Screenshots

Currently, the Native Editor doesn't have the v-model binding option available in its definition. Providing such an option will be a nice to have feature in the component. 

Describe the bug
The Native Editor blocks the browser when used in Vue 2. Meanwhile, the same component configuration works correctly in Vue 3.

To Reproduce

1. Open this CodeSandbox(Vue 2)
2. The project cannot be started or blocks the browser

Expected behavior
The example above should be working like in this project(Vue 3).

If the Editor component has the "required" property it can be easily validated with a simple configuration. 

Currently, the validation of the Editor can be achieved only with custom validation.
