No. It could be a bug in the xbox controller. But I need to take a
closer look at the specification to be really sure.

Thinking out loud: this seems too basic a mistake for an end product
(but I wouldn't be too surprised if this is the case), perhaps something
that we are assuming and is incorrect?

But glad that we found a workaround.
