When editing powerpoint documents nvda incorrectly speaks previously entered but later deleted characters when the space bar is pressed.

This has happened to me in all places in powerpoint. When editing and I write something but mid-way through the word I erase a letter and continue to type nvda treates the deleted character as if it were still part of the word. Here is an example from my power point.

=example=

I am a good leam (press backspace on m) der (Now press space.) NVDA now says "leamder" rather than just "leader". This occasionally leads to confusion when editing powerpoint documents.

I have created a patch for this issue. Now, deleted characters are deleted from the buffer and not taken as part of the word. Changes can be seen here:

Please review and accept.

I can still produce this behavior on my machine.

Steps to reproduce:

1. Open powerpoint.
2. Go to any of the edit fields for a slide, and start typing.
3. press backspace on a character.
4. then type as if nothing happened.
5. Press space.

expected behavior, nvda handles the deleted text as normal.
buggy behavior: Nvda reads the character in the word, as if you had typed it, so for example if I typed nvda, but accidentally typed nb and then deleted the b and replaced it with a v, nvda would say nbvda or that is n b v d a. If this is local to my machine than let me know.

You're still seeing it because no fix was ever committed.

In [5d8aa36]:

In Microsoft PowerPoint with speaking of typed words enabled, characters erased with backspace are no longer announced as part of the typed word.

The typedCharacter event isn't fired for backspace, so we have to fake it.
