Both commands show the Separations Preview panel (#4542), whose Color Settings
section, with the Assign row, comes after the plates and Proof Setup. A
floated panel fits its content only up to 320 points, so the section opened
out of sight and the panel looked like the wrong one. The commands now leave a
one-shot flag that scrolls the section into view, without animation, the next
time the panel draws. Window › Separations Preview and edits made in the panel
leave the scroll alone.
