New Identity doesn't revoke temporary javascript permissions on TBB
In Tor Browser, if you temporarily allow a Website to use JavaScript and use the New Identity button and go back to the exact same website afterwards no script will forget that it granted temporary access to it pre-new identity yet allow scripts to be executed nonetheless
This issue has been reproduced on both Tails 3.3 and Tor Browser 7.0.11 running on Debian stable.
It's been reported on Tails bug tracker first: https://labs.riseup.net/code/issues/15140
