Platform: 0.0.0.0

Steps to reproduce the problem:
1. Enable ChromeVox.
2. Focus on a radio button in a fieldset.
3. Listen to what the ChromeVox is saying.

Note: I'm not sure if this is specific to fieldsets / radio buttons or not.

What is the expected behavior?
In the example I link to below, ChromeVox reads:

"Red, radio button unselected 1 of 3. Choose your favorite color. Red, radio button unselected 1 of 3."

What went wrong?
I should have heard something like "Choose your favorite color.  Red, radio button unselected 1 of 3".

Did this work before? N/A 

Chrome version: 71.0.3559.0  Channel: n/a
OS Version: 71.0.3559.0 (Developer Build) (64-bit)
Flash Version: (Disabled)

I just started using ChromeVox so I'm not sure if it worked before.  It seems like it would have since it's only using native HTML elements, and a fieldset is pretty common with radio buttons.

Here's an example link I put together to help demonstrate the problem.
