calling renderFromHTML with empty string or blank tags causes crash when you click on the editor holder

Describe a bug.

Just as the title says. This is the error you get:

```TypeError: Cannot read properties of undefined (reading 'holder')```

Steps to reproduce:
1. Go to [my codesandbox](https://codesandbox.io/s/editorjs-renderfromhtml-bug-repro-xpl50e?file=/src/index.js) to see a minimal reproduction of the error.
2. Click on where the editor should be, in the browser window.
3. Uncomment the other lines to see it fail with "" and see it pass with non-blank tags or non-blank strings.

Expected behavior:

The editor should render with no content.

Device, Browser, OS: macOS, codesandbox

Editor.js version: latest

Plugins you use with their versions: error happens independently from plugins
