I'm getting the snychronous XMLHttpRequest warning when using the pe:ckeditor on my page:

[Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/. jquery.js.jsf?ln=primefaces&v=6.1:formatted:5880

I've tested it with chrome and firefox. As soon as I remove the ckeditor the warning is gone.

You can also see the warning on the showcase: https://www.primefaces.org/showcase-ext ... cUsage.jsf.

On the official CKEditor sample pages the warning doesn't appear so the cause should be in the PE sources, so I've searched the pe:ckeditor sources on git for a synchronous request and can't find any.

Does anyone have an idea what could be the cause of the warning?
