Web Browser widget loadstring having no effect.

I’m trying to use the web browser widget and loadString to pass in html from a file. I have the file content loading correctly but when I try to drop LoadString() into the blueprint and hook it up, it doesn’t take effect.

If I supply an initialURL to the widget, it loads that, but the load string then never takes effect. I can’t seem to find any examples of it working, so is there an issue currently with loadString?

I’m tying it into the flow after createWidget -> AddToViewPort -> Set Size in ViewPort -> LoadString.

It’s target is correct, and the html content string is being read from a file and passed into the content link in the loadString node, but nothing happens.

Any pointers would be appreciated!
