Browser Undo and Redo do not work in text editor

Start writing a new blog post in wordpress 2.5, for example on wordpress.com. When you've finished writing it, accidentally highlight the whole text and delete it. Press CTRL+Z or Undo in your browser.

If your browser is GNOME Epiphany nothing happens, you cannot undo, you've lost your work.

If your browser is Firefox 3 you can undo. Redo, however, does not work.

In either of these browsers, on most web pages, both Undo and Redo work absolutely fine in the embedded text editor.

I am using Ubuntu 8.04 and am able to reproduce this issue in both Firefox and Epiphany by following the steps above.

I would say this is a pretty serious issue as it can lead to the loss of big chunks of user content. My friend just lost an hour's work and is very upset.

Surely this is handled by the auto-save functionality?

TinyMCE I take it?

Both undo and redo seem to work well in all supported browsers, GNOME Epiphany is not officially supported.
