Names not announced for form fields if their value is not empty

[jteh]

When tabbing or navigating to form fields in a virtual buffer, NVDA reads the name of the field (usually obtained from an associated label) prior to the role. However, if a field's value is not empty, the name is not read.

Reproduceable: always

Steps to Reproduce

1. Go to http://trac.nvda-project.org/.
   
2. Press f once to navigate to the search field. Observe that "Search:" is spoken before the "edit" role.
   
3. Press enter and type some text.
   
4. Press NVDA+space to disable virtual buffer pass-through.
   
5. Press control+home to move to the top of the document.
   
6. Press f once to navigate to the search field again.
   

Actual Results

The "Search:" name is not announced in step 6.

Expected Results

The "Search:" name should be announced.
