Dependency issues on a network installation

I have a network WordPress setup where Plugin Dependencies is activated network-wide. Now, there are two plugins, PluginA and PluginB. PluginB depends on PluginA, like so:

<?php
/**
* Plugin Name: PluginB
* Depends: PluginA
*/


The first issue I’m experiencing is being able to activate PluginB network-wide, regardless of whether PluginA is active or not.

But, most importantly, when PluginA is activated network-wide, PluginB cannot be activated locally, on a single site!

Any thoughts?
