toolbar: {
      container: ['bold', 'italic', { list: 'bullet' }, 'link'],
      handlers: {
        link: () => {
          const editor = reactQuillRef.getEditor();
          const unprivilegedEditor = reactQuillRef.makeUnprivilegedEditor(
            editor,
          );
          const range = unprivilegedEditor.getSelection();

          if (range == null || range.length == 0) {
            alert('nothing is selected');
            return;
          }
          const tooltip = editor.theme.tooltip;

          tooltip.edit('link');
        },
      },
    },

As soon as I click on the Link button the link editing tooltip appears for a brief moment and then closes itself immediately. It all works fine if I remove the handler altogether. What am I doing wrong here?
