If you click "Edit Blocking Tasks" in a task's view, a dialog opens and the search field is focused. If you type something and press enter, the dialog is immediately closed without adding any blocking tasks.
Suggested behaviour:
* If enter is pressed without typing in a search query, nothing happens
* If enter is pressed with a search query:
** If there is only one result, add that as a blocking tasks and close the dialog
** If there are multiple results, do nothing
** If there are no results, do nothing
