[Bug] Setting Android's SoftInputMode to Resize breaks entry focusing on ListView's Header

Description

If we have a ListView with a Header, containing at least 2 entries, setting the Android's UseWindowSoftInputModeAdjust to Resize causes the entries focusing to be incorrect. See the attached project below.

Steps to Reproduce

1. Create a page with only 1 ListView. It can have no records, it doesn't matter. The issues happens with or without items in the ListView
2. Set the ListView's header to a content (StackLayout, Grid, etc) which is having several (at least 1) entries
3. Set the page's SoftInputMode to Resize
4. Try to focus on one of the entries, besides the first one. For the example, let's say that we click on the second entry

Expected Behavior

The second entry is gaining the keyboard focus

Actual Behavior

The second entry is gaining the keyboard focus for a millisecond and then the focus automatically shifts to the first entry
