sample html with text fields

Overview:

Unable to use AccessibilityObject::replaceTextInRange to insert text at first time when the text fields are empty. After the first try, text are able to be inserted. This can be reproduced on text <input>, <textarea> and editable <div>. If there are pretyped text in the text fields, the API works well.

Steps to Reproduce:

1) View any web page with text <input>, <textarea> and editable <div> (attached a text html with these elements).

2) Focus on an empty text field

3) Type (via AccessibilityObject::replaceTextInRange; in our case, we are trying to adopt this API to Braille typing).

Actual Results:

Nothing gets inserted at the first insertion. After that, we are able to insert the text.

Expected Results:

Text get inserted properly even when the text fields are empty.
