Multiline raw string literals breaks coloring and indentation

Using raw string literals containing multiple lines breaks the coloring of the string after the first line (e.g. the text has the default text color and C++ keywords are highlighted).
Starting on the third line, the indentation is also wrong. This continues even after the string is closed until the end of the file.

Example code:

int main() {
	R"(the first line looks correct
	wrong coloring of the 2nd: e.g. 42 int "string"
							   and wrong indentation
							   of the following lines)";
	  // even after the string
	  return 0;
}
