NVDA does not read all of the li elements in a list

element when shown with role="alert". Narrator simply reads "Alert".

If the

• elements are changed to
  or tags, then NVDA can read the errors in the list.

  Actual behavior:

  NVDA only announces "Alert" when error is shown

  Expected behavior:

  NVDA announces "Alert: Error 1, Error 2" when error is shown
