The initial bug report was for Metal L&F, since it has a drastically different button margin from the rest (2, 14, 2, 14). This left and right margin of 14px led to the initial bug report. However, it was determined that the issue was not an issue, and instead, a problem with the reporter's implementation since they weren't aware of the difference in Metal's button margins versus other L&Fs.
