TYPO3 Core

Steps to reproduce:
Create a new record which has a required field. Insert something in the required field. Click on save. The alert "The fields marked with an exclamation mark are not yet correctly filled in. Please complete them properly." is shown.

You have to click somewhere else before you click on save.

Because of the setTimeout in typo3/sysext/backend/Resources/Public/JavaScript/FormEngineValidation.js Line 59-62 around "FormEngineValidation.validate();" the checkSubmit function should also wait 500ms before it tries to submit the form.
