Are you able to reproduce the bug from the demo?

What is the expected behavior? that if there is a set id and it doesnt match any on the page to leave it alone

Describe the bug detailed a \3 and a space after the character following the \3 is injected into the id . . . for example if i have a css with #testID added as component, the reultant id would end up as "#\3t estID" in the css. the html element is the same just not the resultant css that is created

What is the current behavior?

Thanks for reporting this, @anatoli-dp.

The issue with custom ids have a \3 injected into the css and a space after the following letter after the \3 when added to the canvas 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
