fix(12550): adding popular network no longer switches network filter

[vinnyhoward]

Description

Fixed an issue where adding a popular network switches the network filter. For example if the user is on "All Networks" and they add a popular network such as Avalanche, the network switcher reverts to that network, instead it should stay at "All Networks"
