Describe the bug When pressing Shift+Tab to unindent a numbered list, an uncaught error is thrown. I have been able to reproduce this error in every version of SunEditor from v2.43.14 onwards. It appears that this uncaught error was introduced in v2.44.0. The functionality works as expected in version 2.43.14.

To Reproduce Steps to reproduce the behavior:

  1. Create a numbered list and add text
  2. Press enter to create a second line
  3. Press tab to indent the numbered list and add text
  4. Press shift tab to unindent the point and the uncaught error will get thrown

Expected behavior The numbered list should become unindented.
