[Interest] Handle frames and web forms with QWebEngine

[NoRulez]

This is not my tree, it's a simple webpage/webform. But it seems that the new "webengine" can't handle simple tasks like this.

I don't think that the following statement is too complex: document.getElementsByTagName('input')

Best regards
