A preview (the Theme Builder's, developer mode's, or one an automation left on through theme_preview)
replaced every site tab's theme, pane themes included, also on reload; "Theme for this pane" then
showed its choice checked while the page kept the preview. Reproduced live: a preview of Windows 98
turned a Paper pane into Windows 98 until the preview ended. Now a pane with its own theme keeps it;
every other tab shows the preview, as before.
