Plugin change log link incorrect on multisite updates screen

[mindctrl]

In 3.7-beta2-25801 multisite, there's a problem with the link that shows the change log when there's an update available for plugins. I've tested on two clean multisite installs. When visiting the wp-admin/network/update-core.php screen, the "View version x.x details" link is missing the "network" piece of the URL. When the iframe pops, you get the "Install Plugins" screen instead of the plugin change log.

The link is not broken on the main Plugins screen. It correctly displays the change log.

Visit

The link looks like this (note it's missing "network" after "wp-admin")
​http://37beta2/wp-admin/plugin-install.php?tab=plugin-information&plugin=plugin-name&section=changelog&TB_iframe=true&width=640&height=670

The link looks like this (link is correct)
​http://37beta2/wp-admin/network/plugin-install.php?tab=plugin-information&plugin=plugin-name&section=changelog&TB_iframe=true&width=600&height=800

Confirmed. The is_admin and is_network properties of the $current_site global are reset by a new set_current_screen( 'tools' ); call when ​requesting file system credentials in the Automatic Upgrader Skin

I don't think the set_current_screen() call is required anymore, thanks to [25806].

Off the top of my head, that would be correct. Removing it shouldn't cause any problems.

In 25836:

set_current_screen() is now unnecessary in Automatic_Upgrader_Skin, which is good because it breaks things in the network admin.

fixes #25622.
