code block c++ should also accept cc on mobile

Reproduction steps

Type in some C++ code block e.g.

// triggers every industry c++ dev
using namespace std;

Now replace the c++ header with cc

Expected behaviour

cc should work as an alias to c++ for code blocks, as the desktop client and Discord both do this.

Actual behaviour

cc does not work on mobile, but it does on desktop
