Search input in the "Add label" field reappears after deleting it.
Observed behaviour: When a label is to be removed, the label should be removed by clicking on the little (x) button. Instead, it is put back into the search bar. Removing the text fully does not leave the search bar cleared, but instead, the search bar is re-filled with the text of the removed label. Typing backspace multiple times will remove the label.
Expected behaviour: After clicking on a label, it is put into the list of selected labels. When it is removed by clicking on the (x) button, it should be gone completely.
