Math Interaction Not Supported

Rob Hudson

I'm attempting to take a practice math test for school, using portable
Chromium: 75.0.3770.142 (Official Build) (64-bit)
Windows 10, NVDA 2019.2.
When I land on the math problem, NVDA says, clickable. I hit space bar or enter on it, NVDA says, math interaction not supported.
What am I missing to be able to interact with this?
