BUG: Set content function empties the component content

I am trying to use the set function to change the content of a component, but actually the result is an empty component with nothing inside.

This is an example with the code summarized

editor.on('component:selected', () => {
    const selectedComponent = editor.getSelected()
    selectedComponent.set('content', "foo")
  });

Version used: 0.16.44

What is the expected behavior?

The code executed should result in a component with text "foo" inside.

What is the current behavior? The executed code empties the component content.

In version 0.16.34 everything works as expected.

Is there an workaround for this issue or should i stick with 0.16.34 verison ?
