Reproducible demo link
https://codesandbox.io/p/sandbox/exciting-lalande-98d5vw
Describe the bug
How to reproduce the bug?
- Add page with component that has malformed inline styles
- Editor does not load and entire page becomes unresponsive. Firefox shows "This page is slowing down firefox" warning
What is the expected behavior? If editor cannot parse CSS, it would be nice to log the error in console and not block the entire app
What is the current behavior? Editor becomes unresponsive
If is necessary to execute some code in order to reproduce the bug, paste it here below:
editor.Pages.add({
component: '<h3 style="text-align: center; /* margin-top: 20px;">Test</h3>',
});

Thanks for reporting this, @tim-prom.
Great question about Malformed inline styles causing editor freeze. 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));
If you're still stuck:
- Share a minimal CodeSandbox reproduction
- Include what you've already tried
