Popout not showing popout icon for World Of Darkness 5e Actor and Item windows

[maxlovell73]

It would be great if World of Darkness 5e Actors and Item windows would work with the PopOut module, as it frees up game window space to move them onto a separate screen during gaming.

I'm using:
Foundry Version 12 Stable build 331
World of Darkness 5e 5.0.8
PopOut 2.18
libWrapper 1.13.2.0
Dice So Nice 5.1.3

The other Foundry windows feature the PopOut icon/button but not Actors and Items.

In the image below the PopOut icon can be seen in thetop right of the Module Management window and not in the Item window (Armour: Kevlar vest/flak jacket)

The authors of the World of Darkness 5e system say they have updated their sheets to AppV2 sheets, and the popup module needs to be updated to work with those sheets going forward.
I tried the changes suggested in WBHarry's pull request, #130, but that didn't get the icons to appear.

Regards,
Max.
