Issue

Markers are not working properly with multiple constraints dependencies as stated in the docs

I am trying to install a dependency from an URL based on the platform, different URLs for every platform (markers = "sys_platform == 'linux'") and poetry is picking the URL from the platform darwin when I'm under a linux platform

I have not tested yet what happens on a Darwin platform. Will update the issue when I do

Update:

If I reverse the order of the dependencies, the first line the darwin url, it works on Linux. The same behaviour applies on Darwin
