Virtual controller buttons are weirdly sticky

[jbmorley]

There's a strange behaviour (regression?) with the virtual controller whereby keys don't release until the last key is released. This makes it very hard to use. For example, if you press and hold left, then B, then release left, it won't actually get released until you also release B.

Weirdly this is an Apple provided control, and there's almost nothing we're doing (or can do) to customise this behaviour, so it's quite possibly a regression in iOS.

Pushing into future as it 'works', just badly.

I wonder if this is also a regression caused by the introduction of a UISplitViewController?
