I suspect they've implemented this horrible pre-connect feature
that firefox and chrome have done as well.

You can add "option http-ignore-probes" to make them disappear.
HAProxy will then silently close connection which time out while
waiting for a request. However keep in mind that it can also hide
some real network issues (eg: MTU issues during POST or things
like this). But since broken brothers are much more common than
broken VPNs these days, most people will probably prefer to hide
these errors anyway.
