When using a password manager like Dashlane with a11y enabled, Firefox crashes with a stack overflow after pressing the "Enter Passcode" button in Mozilla's 2fa.
When the button is pressed the text field is shown and the button turns into a sign in button. It looks like that simultaneous tree mutation and focus change puts us in a state where the viewport cache has one hierarchy, and the focus cache has another. This causes a state where we end up in a parent/child cycle.
