Thanks for the details.
Other than UI components not getting loaded properly, i don't see other reasons for this inconsistent failure. I updated the test and added small delays to avoid these unexpected failures.
Added more number of items as well to the choicebox in the test so that while scrolling in larger screen we don't run out of options in the choicebox which results in hiding of down arrow which leads to test failure.
