sample html with text fields

Summary:
When calling the replace with range API for a web textfield, VoiceOver does not get an AXValueChanged notification from the web area like it does when typing with the keyboard.

Steps To Reproduce:
1. Open a web page with a web textfield. (text.html)
2. Type in the first textfield with VO and a Braille display

Results:
VO gets a AXValueChanged notification for the textfield, and an AXSelectedTextChanged notification from the web area. These same notifications come in when typing with the keyboard. The difference is when typing with the keyboard, VO also gets an AXValueChanged notification from the web area. There should be a AXValueChanged notification since calling the API changes the value of the textfield.

Regression:
No
