Fixes regression bug where Aqua L&F editable JComboBox with a TitledBorder was not visible.
This fix adds a conditional that addresses cases where a border is used on an AquaComboBox. The patch that caused the issue set a static height, but this height caused issues with a TitledBorder, which modifies the height to account for the border. In this case, revert to the old method of calculating a comboBox's height. A point made in the previous PR was that the previous method had +1 to comboBox height. This could be re-added, but in the comment thread in [the previous PR](https://github.com/openjdk/jdk/pull/12087), leaving this out is better because the extra height causes the textField to be skewed South. <img width="63" alt="Screen Shot 2023-01-20 at 12 54 47 PM" src="https://user-images.githubusercontent.com/96267980/214998560-2340ac1d-5df3-47ba-94f7-56459211330e.png";> This also adds the test that checks an editable JComboBox across all L&F's except GTK. There seems to be an unrelated bug to this fix that causes GTK L&F comboBoxes to not behave as expected with these key presses. ------------- Commit messages: - Change line separator - Fix carriage return - Fix height issue with border.
