fix(desktop): keep profile color picker open from the context menu (#45489)

Right-click → Color flashed open then closed: on dismiss the context menu
refocuses its trigger, which doubles as the popover anchor, so the picker
read it as a focus-outside event and closed itself. Suppress the menu's
close auto-focus so the picker survives. Long-press already worked since
it bypasses the menu lifecycle.
