Undo doesn't work after a Component's innerHTML is changed
UndoManager tracks component state changes, not its DOM. This should work in your case element.components('Hello Planet')

Describe the bug
How to reproduce the bug?
- Change a Component's innerHTML
- Press CTRL + Z
What is the expected behavior? To undo the content
What is the current behavior? Doesn't undo the content
Description:
On the fiddle, press the button that says 'Change to Hello Planet' and then select the editor and press CTRL + Z
and the undo won't work (nor the redo), but if you change the 'Hello World' text normally it works fine.
I think I'm changing the content wrong? and if so what's the best way to change a component's content and emulate the native behaviour

@artf Thanks!
Thanks for reporting this, @leo-budgetsimple.
Great question about Undo doesn't work after a Component's innerHTML is changed. The recommended approach with UndoManager is to use the event-driven API.
Start here:
- Check the GrapesJS documentation for your specific module
- Look for the
on()event listener method - Most operations can be achieved by listening to editor and component events
Common patterns:
// Listen for changes
editor.on('change', () => console.log('something changed'));
// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));
