Trying to load these settings triggers an "Error: Bad Request" alert (including when loading settings you just saved):

• BraceWrapping
• ForEachMacros
• IncludeCategories

You can also use the Linux kernel .clang-format file (https://github.com/torvalds/linux/blob/master/.clang-format) as a test case.
