Undocumented behavior when `input: 'string'` is mixed with `stdio: 'inherit'`

I'm not sure how to make a repro because I've only encountered this issue with SSH. If I `ssh bash` piping in a script with `input: '<bash script>'` and I have `stdio: 'inherit'`, the command never exits after running the script. But if I change to `stdio: ['pipe', 'inherit', 'inherit']` it does exit normally. In retrospect it makes sense that mixing `input` with `stdio: 'inherit'` might not work, but this was fairly confusing, and I don't see any documentation of what's supposed to happen in this case. Would it be better to error out, or automatically force `stdin` to be `'pipe'` when `input` is given? Or is there some kind of legitimate use case for mixing `input` with `stdio: 'inherit'`?
