"Check parameter for null" generates if without braces as configured

Having:
ReSharper > Options > Code Editing > C# > Code Style > Braces > 'In single-statement "if-else"' = Required

When using "Check parameter for null", it generates invalid code:

if (a == null)
  throw new ArgumentNullException("a");

... instead of expected:

if (a == null)
{
  throw new ArgumentNullException("a");
}

... this drives me bit crazy, can't find other settings affecting this, code template, anything :) I would much appreciate if anyone could point me where to set correct/expected behavior.

I'm using ReSharper 10.1 EAP, VS 2015 - 14.0.24720.0
