• Describe the issue you encountered:
  If you enable 'Block Scripts' from the Bravery icon, scripts are blocked, but the toggle still shows off. You are unable to 'undo' this action from Bravery icon.
  Additionally, if you have 'Block Scripts' enabled by default, you can click on it to unblock scripts from the Bravery Icon, but the toggle still shows on.
  This was working in 0.18.20

  MacOS

• Brave Version (revision SHA):
  Brave | 0.18.21
  rev | 263b6d5

• Steps to reproduce:

  1. Clean install of 0.18.21
  2. Open tab and navigate to brianbondy.com.
  3. Click on shields.
  4. Select toggle for Block Scripts.
  5. Content on brianbondy.com is not loaded, but toggle still displays as off (gray, not orange).
  6. Additionally if you close shields, you cannot allow script from the URL bar.

• Actual result:
  Toggle displays off, you cannot undo the action from the shields.

• Expected result:
  Toggle should display on, and you should be able to undo your selection.
