If the Preview tab is the active tab in the vault client and you select a file from the browser, as soon as the visualization loads, focus is taken from the selection in the browser.
This means that if you are changing the category of lifecycle state on the file and the preview pane is selected, you have to select the file, wait for the visualization to load, then reselect the file in the browser... every single time you want to do something.
No portion of the UI loading should steal focus from a selection. It should only change when the user makes a selection or clicks on another area of the ui.
