I'm working on an a webapp, where I need to adapt the contents of the screen when the virtual keyboard is expanded. Luckily, someone has already created an example of this here:

When tapping on the text area, it correctly resizes. However, there is a small delay between the tap and when the resize happens in iOS 15.5. This is because the resize event doesn't seem to fire fully until after the keyboard is expanded. In iOS Chrome, interestingly, this does not happen and it works correctly.

Are there any workarounds to get Safari to fire the event sooner? Or alternative approaches to achieving a similar effect?
