When setting the width of the textarea there were some issues preventing this from working correctly. These problems included: - If the maximum width needed to be used, the width of the textarea did not take into account the prompt and line number width. - The viewport width did not take into account the style width. The entire function was confusing to understand and a refactor was warranted. As part of this refactor, the bugs mentioned above were fixed and the code was simplified. To verify that the logic works as expected, unit tests were expanded to validate that setting the width works as expected. Signed-off-by: Michael Lorant <michael.lorant@nine.com.au>
