Some content types generates "The text field is required and must have a value." error over and over again when you click on the title of the content block to collapse it.
This should be expected behavior:
User clicks on the title line.
Gets error message "The text field is required and must have a value."
User clicks on the title line again.
Error message is still here and he gets red border around missing field.
Next time the user clicks on the title - nothing happens.
It is very clear that he need to fill this field/fields since he has both error message and border around the field.
User selects the field and start typing - border and error msg below hides.
Error messages should not replicate over and over again after clicking on a title of a content block.
