Match the whole word in Find it does not match

[Aneta]

1. Hit the Find button and type a word from the text.

2. Tick only - match the whole word and click on Find button.

Result: A notice pops out - The specified text was not found.

Are you using a specific browser?

Ok, it looks like this problem doesn't happen always. I found a way to reproduce it consistently though:

1. Load the editor and remove all the text on it.

2. Manually type three paragraphs, each one containing one of these words, in this order: "test", "try" and "test".

3. Move the caret to the start of the text.

4. Open the Find dialog.

5. In the "Find what" field, type "try" and hit the "Find" button. The word will be correctly found.

6. Hit "Find" again. A js error is thrown.

7. Close the dialog.

8. Repeat steps 3 to 5. It will not work anymore. Actually, the Find dialog will not work anymore until reloading the editor.

Confirmed with FF3.

Updated Garry's patch with respect to the current trunk for easier reviewing.

Review- because the patch doesn't seem to fix the problem described in comment:2. I'm still getting the not found problem when match whole word is ticked.
