I have issues with colopicker strugling with proper color convertions

Thanks for the report. This should have been fixed here https://github.com/GrapesJS/grapesjs/pull/6672

for ex: #ff000077 (transparent red) is being converted to #000077 (shade of blue).

I tried monkey patch it but seems like internaly grapes js uses its own implementation not the one bound to window. (unfortunately for me)

Would be nice to have this fixed or those utiliies exposed for customization. Thank you.
