1831734 - Multiple undo / redo.

Status: UNCONFIRMED

(SeaMonkey :: Composer, enhancement)

Description

[Pascal]

Steps to reproduce:

I type some texts and modify other texts then select menu Edit->Undo several times and also Edit->Redo.

Actual results:

Only the first undo is effective.

The redo is not working at all neither for the first undo nor the others.

Expected results:

I expect that many undo working pair with redo.
