Steps to reproduce the problem:
1. Submit an HTML form on a page that redirects back to itself (with the same form)
2. Open Developer Console (F12)
3. Refresh the page with the HTML form
4. No prompt is displayed to confirm resubmitting the form, but it does resubmit the form

What is the expected behavior?
The prompt should be displayed to Confirm Form Resubmission, or there should be some setting in the Developer Console to toggle this behavior

What went wrong?
4. No prompt is displayed to confirm resubmitting the form, but it does resubmit the form

Did this work before? N/A 

Chrome version: 69.0.3497.100  Channel: stable
OS Version: 10.0

Apologies if this is intended, but it seemed odd that if it was, there was no setting in Developer Console to toggle the behavior.  It led to a Sev 1 issue before our product release because we thought our backend form logic was broken, when in fact it was just being resubmitted by the browser on refresh without us knowing.
