Compilation error with feature flags

[flat helm]

You mention an error: are you getting the "Cannot have both sys and js features enabled at the same time" error as well?

I was asking because since features are additive, it can happen, in certain cases, that somehow you'd end up with both features being added. And if so, you might have reached the compile_error!() case, but Rust might have tried to keep compiling other stuff to give you as much actionable info as possible, thence resulting in the overlapping reëxports
