Here is an insane workaround for the inpatient developer:
Open the Chrome debugger.
Click the "Pay this fee now" button.
Check out the console. There will be a an undefined variable due to a race condition in the Google production code. Put a break point at that location (at the location in red above).
Click the "Pay this fee now" button again. Let the debugger break at the your breakpoint.
Copy the "params" parameter (in your console window):
window.params = params;
Continue the debugger (play button).
now manually call the function that broke using the params object you stored:
window.google.payments.inapp.buy(window.params);
The payment modal will show up.
Voila.
