Formatter inserts unexpected whitespace in if with comments after macro

Bug Report

This:

macro x

end

if true    #
  a = "xy" #
end

... formats to this:

macro x
end

if true #
  a = "x   y" #
end

Macro with leading/trailing newlines. Code could be between the macro and ifs, in my case that was several hundred lines:

macro x

end

dofoo(1)
foodo(2)

if true    #
  a = "xy" #
end

... becomes:

macro x
end

dofoo(1)
foodo(2)

if true #
  a = "x   y" #
end

Similarly with multiple ifs:

macro x

end

if n0 #
  a = "xy" #
end

if n01 #
  a = "xy" #
end

if n012 #
  a = "xy" #
end

if n0123 #
  a = "xy" #
end

if n01234 #
  a = "xy" #
end

if n012345 #
  a = "xy" #
end

... formats to:

macro x
end

if n0 #
  a =      "xy" #
end

if n01 #
  a = "    xy" #
end

if n012 #
  a = "x   y" #
end

if n0123 #
  a = "xy  " #
end

if n01234 #
  a = "xy"  #
end

if n012345 #
  a = "xy" #
end

There's also this:

macro x
  
end

if 1 #
  foo #
  xyzzy = "hello world" #
end

... which formats to:

macro x
end

if 1 #
  foo                    #
  xyzz                  y = "hello world" #
end

... and so on.
