PIN screen does not always show digit buttons 9 and 0

The test fails half of the time with the following error:

java.lang.Exception: ══╡ EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK ╞═════════════════
The following assertion was thrown running a test:
The finder "zero widgets with text "Prefer a shorter PIN?"
(considering only hit-testable ones) (ignoring offstage widgets)"
(used in a call to "tap()") could not find any matching widgets.
When the exception was thrown, this was the stack:

The test description was:
change-pin

On some phones the buttons to enter the digits 9 and 0 sometimes fall off the screen. Not all failed test cases point in the direction of this, so it could be that there are more issues.
