This PR was submitted for the master branch but it was merged into the 4.4 branch instead (closes #13349). Discussion ---------- Make it more obvious what the $handler is on Messenger docs fixes #13148 As mentioned in the issue `$handler` was not obvious. I referenced the next item in the docs in the hope that this makes things more clear. This issue is present on other versions of the documentation but the behaviour of the function also changed (parameter now can be an array). I am unsure of how to proceed in such a case.
