Text input in npc dialogs doesn't process enter key

[samtigall]

Whenever a text input opens you cant use enter to proceed and you need to mouse click the ok button.

Example: Merchant Quest Delivery Box Number Input.

I think the issue here is that new window isn't focused so enter is still working with the chat.

This was working before, but maybe something broke it. It deffo needs to set the focus on the popup. Maybe even needs placeontop()

fixed together with #378, at #401
