Maui Keyboard Bugs both with AdjustPan/AdjustResize

[cerkzil]

Description

There was previously reported issues with AdjustResize and one of the solutions recommended by people was to use AdjustPan,
which doesn't actually solve the underlying issue and only helps if you have small amount of inputs right at the top.

Here my comment pointing that out: #11274 (comment) sadly topic was already closed as solved so I'm opening this one here with even more info.

Here are screenshots from my demo application (the green background is from a page below in navigation stack):

From what I understand the issue is that both AdjustResize/AdjustPan don't recalculate the height of the page properly after closing the keyboard.

Steps to Reproduce

1. PushModalAsync(new Page()).
2. Have any text inputs that fill the whole screen.
3. You will see previous page being shown.
