Steps to Reproduce

Run the script above and click the "Capture Exception" button.

Expected Result

User feedback should be sent normally.

Actual Result

The app throws the error Sentry.sendFeedback is not a function. I also tested this in my own test application and got Failed to send feedback: window.Sentry.sendFeedback is not a function in the browser console.
