Crash log

This seems to reproduce on any site with a date picker element, e.g. https://go-mini.com. I've been able to reproduce this crash in both Safari and Chrome on iOS 17 beta.

Steps:
1. In Safari on iOS 17, visit a site that has a date picker.
2. Reload the page and quickly tap on the date picker (might take a few tries to get the timing right)

This results in an exception:
CALayer bounds contains NaN: [#.# #.#; #.# #.#]. Layer: <CALayer:0x#; position = CGPoint (# #); bounds = CGRect (# #; # #); delegate = <_UIDatePickerOverlayPlatterView: 0x#; frame = (# #; # #); transform = [0, 0, 0, 0, 0, 0]; layer = <CALayer: 0x#>>; sublayers = (<CALayer: 0x#>, <CALayer: 0x#>); opaque = YES; transform = CATransform3D (0 0 0 0; 0 0 0 0; 0 0 1 0; 0 0 0 1)>
