I just wanted to note that we ran into an issue with New Relic after adding the Content-Length header. It wouldn't inject the js-agent into the html because there was a Content-Length header (probably because it changes the length by doing so). So, we stopped getting PageView information until we removed the header.

One work around is to add the script tag manually in code. That way you get the correct Content-Length and you don't rely on it being injected automatically by the php agent.

Attaching patch.
This patch is allowing a site I'm working on to run in both Drupal 9.5.x and 10.0.x with version 2.0 of this module. It probably does not work for Drupal 9.4 and less.
I updated the handle method to match how core is using it:

kleinmp → created an issue.
I re-roled the patch off of drupal 8 and hopefully fixed the simple test issue.
Here's the patch re-roled against the newest drupal 7 dev.
