Regression?

[Gregg Smith]

When setting a header it used to set the header case-sensitive as 
configured. Now with 2.4.38 it sets in all lower case. Regression?

Header always set X-Xss-Protection "1; mode=block"
Result;
2.4.37: X-Xss-Protection: 1; mode=block
2.4.38: x-xss-protection: 1; mode=block
If I'm reading the RFC correctly, sensitivity doesn't matter when 
parsing the header but the 2.4 docs show it outputting as configured as 
2.4 has been prior to .38.
