Akita icon shows monetization badge on FB messenger

[sharon-wang]

Describe the bug
When a monetized site is opened in one Chrome window and you navigate back to a Messenger call in another Chrome window, the Akita extension image remains on the non-monetized (no tongue) image, but the monetization badge shows up. This is bizarre behaviour...

To Reproduce
Steps to reproduce the behavior:

1. Open a full-screen Chrome browser window and call someone on Facebook Messenger (make sure they pick up :P)
2. Open another full-screen Chrome browser window (not another tab, make sure it's another window) and go to a monetized site
3. Note that Akita displays the following icon on the monetized page
   
4. Go back to the Messenger call window
5. See the Akita icon bug
   

Expected behavior
The regular non-monetized icon with no dollar sign badge should show up on the messenger window because messenger is not Web Monetized...

Desktop (please complete the following information):

• OS and Version: macOS 10.15.5
• Browser and Version: Chrome Version 84.0.4147.135 (Official Build) (64-bit)

Just a note to us that #84 did not resolve this problem. We're still not sure why this is occurring. Maybe we should test to see if a similar problem also occurs with the Coil extension?
