Insert styles from StyleManager with !important broken

Quick answerby ClaudeCode

Thanks for reporting this, @clonefunnels. The issue with insert styles from StyleManager with !important broken appears to be a race condition or state management timing problem.

### Describe the bug

When I use this code it stops working after one div change and then no longer accepts any more style changes to any other divs:
editor.on('styleable:change', (model, property) => {
        const value = model.getStyle()[property];
        if (value.indexOf('!important') === -1) {
          model.addStyle({ [property]: value + ' !important' });
        }
});

When I use this code it inserts thousands of !importants and breaks the style:

editor.on('styleable:change', (model, property) => {
      const value = model.getStyle()[property];
      console.log('Styled ', property, value);
      if (styleImportant) {
        model.addStyle({ [property]: value + ` !important` });
      }
    });

These are the only two solutions I have been able to find in the project discussions.

If you have one that works, please let me know, or fix the bug.

Thanks for reporting this, @clonefunnels.

The issue with insert styles from StyleManager with !important broken appears to be a race condition or state management timing problem. This typically happens when component lifecycle events and DOM modifications overlap, creating an inconsistent state.

What to try:

Add a setTimeout wrapper to ensure the DOM has settled:

setTimeout(() => {
  // your operation here
}, 0);

Check initialization order — make sure components are fully loaded before you interact with them
Use the editor's event system — listen to completion events:

editor.on('component:mount', (component) => {
  // safe to interact with component here
});

Recommended next steps:

Test with the latest GrapesJS version if you haven't
Provide a minimal reproducible example (CodeSandbox) — this helps the team identify the root cause faster
Include GrapesJS version, browser, and console errors in your report
