When the passwordless unlock screen with an "Unlock" button is shown, you can't press the button by immediately hitting the Enter or Return key. You need to first focus it by hitting the Tab key twice, and only then can you press it using the keyboard.

Git commit 370976d71582c4d057147dd6f123acc4bcf5d010 by Nate Graham. Committed on 01/06/2022 at 22:21. Pushed by ngraham into branch 'master'. NoPaswordUnlock screen: focus it by default Otherwise the user needs to manually tab over to the Unlock button first, which is annoying. And they may not even think to do it at all. The `forceActiveFocus()` is because the stack view does not manually pass focus to the item you push onto it; this needs to be handled manually.
