textarea caching issue in chrome

[pacific202]

I have a very strange issue in Chrome where a textarea in a dialog seems to cache the previous value, but IE7 works exactly as you would expect.  I have attached the file I'm working on.

To reproduce this:

1. Enter a JSON string in the "JSON" field.  This one works well for this purpose:

{"a":"b","c":"d"}

2. Click the "From JSON" button to translate the string into the propertyeditor.

3. Select one of the rows then click "Edit" to bring up the dialog.

4. Change the value then click "OK"

Note that there is a dependency on jquery.json-2.3.min.js in order to parse the strings.
