Status category "Installed (auto removable)" inconsistent directly after cancelling uninstall that would lead to further uninstalls

Description

The category "Installed (auto removable)" is inconsistent if opened directly after cancelling a uninstall that would cause further uninstalls.

• Have packages A and B installed, with B being both manually installed and depending on A.
• Request uninstalling the dependency A.
• In the "Mark additional required changes" dialog that asks to also uninstall B, hit "Cancel"
• Both A and B are listed under "Installed (auto removable)" if and only if that is clicked as right the next action after cancelling. Doing something else first updates the internal state to correct this, and neither A nor B show up as automatically removable.

I assume the auto removable category is updated as soon as the user hits "Mark for removal", and cancelling the additional changes dialog does not revert those updates.
