Fix #8445: View recovery phrases button is not tappable

[nuo-xu]

Summary of Changes

This issue is caused by the ScrollView has the wrong frame even though screen size is big enough for it to expand. With further investigation, wrong frame caused by keyboard not being dismissed in the previous step which cause SwiftUI thinks the screen height is the actual height minus keyboard height. Attached screenshots below to see the height differences.
