The help path is formed incorrectly for functions in pxt-helpers.ts. The "/reference/" path prefix isn't prepended to the function's help= subpath as needed. The reference doc path is ./reference/math/abs.md so the render code needs to add the ./reference/ piece. This is a pxt bug.

//% help=math/abs
export function abs(x: number): number {
    return x < 0 ? -x : x;
}
