Blur doesn't follow Dialog on Android 33 about haze

[chrisbanes]

Just had a quick look into this. So we map all hazeChild positions using positionInRoot (root being the root composable), which is the simplest way to handle this 95% of the time. Dialogs however are put into their own android.view.Window on Android, which means that they're not part of the original root composable. They have their own root composable, with its content being displayed at 0,0, hence why the blurring is at the top left.

To fix this we need to calculate everything in 'screen' coordinates, by passing along the window offset when sending the hazeChild positions. That's not particularly difficult, but we need to do it in a way which works across platforms, which is probably going to be trickier.

Got a small repro sample? I'm not surprised this doesn't work out of the box to be honest
