Do not block tabs by $popup modifier which are opened by a user

Browser version

Chrome 116

OS version

macos 13.5.2

Steps to reproduce

1. add a rule $popup,domain=iana.org
2. go to example.com
3. open "More information..." link in a new tab

Result:
The new tab is closed by the rule but it shouldn't be.
the same happens when the tab is opened by js in the console:

window.open('https://www.iana.org/domains/example')

The main problem that there is no way to detect which tab is opened by a user manually and which one is opened programmatically. $popup modifier rule is applied on the onBeforeRequest event where isNewPopupTab() returns the same result for both cases — true, and the tab is being closed.

It would be helpful if the details object has a new boolean property, for example, initiatedByUser, because now all other properties do not provide enough data to calculate it:

Expected Behavior

Tab opened by a user should not be blocked by $popup modifier rules

after the issue is resolved, it may be possible to handle logging of $popup rules:

@@ — a marker that is used in rules of exception. To turn off filtering for a request, start your rule with this marker.

So I think you need to use: @@||iana.org^$popup
