Hey Martyn,

Yes this is still a bug. But this patch doesn't address this case.

And this is a major problem when it comes to multiple bridges of differing
types. What I'm saying is that this patch simply fixes this one problematic
case. We can move this out as soon as we have a more robust implementation.

As of now however, I think applying this is useful as we have a decent
workaround to the problem. If you want I can make the fact of it being
applicable only to cases with differing bridges explicit in the commit
