Bottom text is covered by virtual keyboard' address bar

iOS 15 Beta 8

VisualViewport.height returns a pixel size that does not account for the address bar above the Virtual Keyboard.

This causes elements that are aligned to the bottom of the page, based on VisualViewport.height, to be hidden by the address bar above the Virtual Keyboard.


I created a test page at https://matan-hershberg-nuance.github.io/ios15-beta-visualviewport-bug/

The test page has an input box, and a paragraph tag that aligns to the bottom of viewport based on VisualViewport.height values.

When clicking the input box and the Virtual Keyboard goes up, the address bar covers the "Bottom" text.

I believe this was not reproducible in earlier versions of the Beta.
