TypeError: e.getRoot is not a function (Race condition in Style Manager)
Similar to https://github.com/GrapesJS/grapesjs/issues/6705 I'm not able to create that kind of race condition (eg. select and remove via API) and in your example is checking getRoot on a component, but there is no such a method on the Component API

Describe the bug
How to reproduce the bug?
- Initialize a GrapeJS editor
- Select a component in the canvas
- Quickly delete the component (press Delete key or use delete command)
- Style Manager's debounced update callback executes after component is destroyed
- Observe
TypeError: e.getRoot is not a function
What is the expected behavior? The Style Manager should validate that components are still valid before attempting to call methods on them. Either:
- Filter out destroyed/invalid components before processing
- Add try-catch guards around component method calls
- Check component validity (e.g.,
typeof component.getRoot === 'function') before invoking methods
No error should be thrown when components are removed during async style updates.
What is the current behavior?
GrapeJS throws TypeError: e.getRoot is not a function when the Style Manager attempts to update styles on a component that has been destroyed or removed from the DOM. This is a race condition between component selection/style updates and component removal/destruction.
Error messages:
Chrome:
TypeError: e.getRoot is not a function
Safari:
TypeError: e.getRoot is not a function. (In 'e.getRoot()', 'e.getRoot' is undefined)

Same as https://github.com/GrapesJS/grapesjs/issues/6705#issuecomment-3921025039, the issue was in our external library that was using GrapeJS and since had same situation like the issue 6705, I will close it. Thank you for your review.
Thanks for reporting this, @saeedhbi.
Great question about TypeError: e.getRoot is not a function (Race condition in Style Manager). The recommended approach with StyleManager 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));
