PopupsAllowedForUrls GPO needs example notation to make it work

Dear reader,

We found out while configuring the GPO setting PopupsAllowedForUrls that it requires the notation:

[*.]han.nl

[*.]youforce.biz

These are 2 settings we had to add this week.

In my knowledge the [*.] is in the documentation (https://docs.microsoft.com/en-gb/deployedge/microsoft-edge-policies#popupsallowedforurls) foe explanation, so you should be able to use:

han.nl

youforce.biz

or:

*.han.nl

*.youforce.biz

But... that is the case. Domain names without any *. or with *. just do not work.

Since in IE and EdgeHTML is was always, and preferred to use just domain names, this almost looks like a bug, if Google Chrome would behave differently, which it does not.

It has the same quirk.

Is this intentional or a bug in Chromium?

We have seen this behaviour in Edge 80.0.361.62 stable on Windows 10 1903

Regards, Henno
