there seems to be a bug in WebBrowserComponent on iOS, although it may be an iOS bug. If you create a WebBrowserComponent and view a page on the iPad in landscape orientation (simulator or real device) then a dropdown lists will drop down horixontally, even though the web page is rendered in the correct orientation. This little snippet is enough to demo that
Must be due to the way the juce windows use a transform to rotate themselves when the device is rotated, but I don't know why the web-browser doesn't also automatically adjust..! There must be some kind of special iOS setting that needs to be used to tell the browser what's going on, but I'm stumped..!
