Outgoing then push doesn't update the filter text correctly
Created originally on Bitbucket by mikezx6r (Mike Wilkes)
This assumes the filter toolbar is visible.
If I do an outgoing, and have changesets, I get the Push/Cancel buttons.
If I select Push or Cancel, the correct action is taken, and the graph re-appears unfiltered, BUT the filter textfield still says outgoing().
Clicking the red x beside the filter toolbar correctly reverts the textfield to the greyed out ### revision set query ###
