3346749 - Issues with locking and copy&paste of texts in Recipe Development

During working with a WebDynpro application, like Display Specification or Display Recipe one of the following symptoms were noticed:

1. Closing a browser tab where an object (specification, recipe, label etc.) was  opened in change mode,  the same object can not be opened again because of an error message that the object is locked by a user. 
2. Copying a text (for example from Microsoft Word) and paste it into a longtext box in a Recipe Development application (for example into a User Defined longtext field of a specification) some spaces between words from the original text disappear (like this -> likethis).
