Pressing F1 while viewing program info causes hang-like behaviour

[John Veness <John.Veness.mythtv@…>]

Steps to reproduce:

1, Go into Watch Recordings
2, Highlight any recording
3, Press I
4, Press F1

At this point the frontend seems to hang. You cannot scroll the program info window up or down and cannot press Esc to back out. However, a second press of F1 brings it back to life.

$ mythfrontend --version

It's actually working as it should.

The web browser mythui widget needs to know where the key presses should be processed either by myth or by the Qt QWebView browser widget we use behind the scenes. For example if you press 'm' should that open the popup menu or should it enter an 'm' in an edit box on a web page? In order to toggle where key presses get handled there is a TOGGLEINPUT key binding (set to F1 by default) which switches where key presses get handled.

Without it there would be no way to enter many keys like 'm' or 'i' in a search edit on a web page for example because myth would get the key before the web page.
