How to reproduce:
- Open Tor Browser.
- Select "High" Security Setting.
- Go to https://github.com/
- Click on NoScript icon and choose "Temporarilly allow all this page".
- You can note that when the page gets refreshed the canvas prompt is displayed.
- Select New Identity in the Torbutton.
- Go to https://github.com/
- You can notice that the canvas prompt is displayed (meaning JS is enabled, which in turn implies that "Temporarilly allow all this page" gets inherited when New Identity is chosen.)
