[Affected versions]:
Nightly 66.0a1 - Build ID: 20190123070847

[Affected platforms]:
Windows 7/10 x64
Mac OS 10.14
Ubuntu 18.04

[Steps to reproduce]:

1. Go to cnn.com/videos - the playback is blocked, blocked icon appears in the URL bar and blocked information is displayed in the Site Information panel
2. Open several other random tabs
3. Right click on the tab with the cnn video
4. Select to Move Tab -> Move to New Window

[Expected]:
The Tab should be moved to a new Window as it was in the original one.

[Actual Results]:
The Blocked icon, as well as the info under Permission in the Site Information panel, are no longer displayed. The video is still blocked but the user has to refresh the page in order for the above items to be displayed again as expected.

Hi, Dale,
Do you mind take a look for this one?
Thanks.

Good catch, can reproduce, I think this is related to https://bugzilla.mozilla.org/show_bug.cgi?id=1522058 and an issue with us showing the blocked icon based on an event vs based on state, I think we are likely going to want to set a property on the tab that gets cleared on refresh when we see the event, and show the UI based on that state

Actually I don't think I need to track this as it seems unlikely to block the feature.

ok got a working patch for thi, just need to write a test for it, looking around for one thats similiar
