Attachment: window.open() "workaround"

Able to reporduce at Firefox 75 and Nightly 77 https://bugzilla.mozilla.org/show_bug.cgi?id=1626573#c13.

One "workaround":

1. Copy the Blob URL at <a> element at STR
2. Navigate to https://mdn.mozillademos.org
3. Open console and run window.open("blob:https://mdn.mozillademos.org/0326019d-c9b5-4483-b8c2-468c9df4f866") or the current Blob URL

Even pasting the Blob URL at the same domain and origin displays the content, without using window.open(). Cross-origin navigation to a Blob URL appears to be disabled?

Attachment: Bug 1628608 - P2 - Browser Mochitests added to test if loading a blob URL in a new foreground tab works r=baku

Two cases have been tested:

1. Loading a blob URL, which points to a blob of type text
2. Loading a blob URL, which points to a blob of type html, which fetches another blob URL

Depends on D71889
