Invalid codegen: if-`@as`-if

const std = @import("std");

pub fn main() void {
    var fast = true;
    var very_fast = false;

    const num_frames = if (fast)
        @as(u32, if (very_fast) 16 else 4)
        //if (very_fast) @as(u32, 16) else @as(u32, 4)
    else
        1;

    std.debug.warn("{}\n", .{num_frames});
}

This prints 16. The commented out line works normally (prints 4).
