getScreenSize() returns wrong height in BlackBerry WebWorks application

This is a know problem in BlackBerry WebWorks, see for example here:

Can be reproduced on any test using a ScrollableView and packaged as a WebWorks app. The problem appears when you rotate to landscape and back to portrait, and also when editing text once the keyboard goes away. The view appears smaller (in height) than the screen size.

The properties that we normally use ( or win.doc.documentElement.clientHeight) all return inconsistent results. The only thing that works in screen.height, but this must be corrected by the devicePixelRatio, which unfortunately is also wrong in WebWorks (always 1).

A workaround could be to use screen.height and correct it using a ratio computed at startup (where innerHeight seems correct).

This also implies to modify the dojox/mobile code where the screen height is retrieved directly through innerHeight or similar, instead of going through getScreenSize().

Given how much WebWorks? has changed, and how few people are using WebWorks? unfortunately, I'm inclined to close this out. Setting to pending, please reopen within 2 weeks if you think this is still relevant.
