(drive-by analysis/notes, since I happened to hit this on a try run):

Here's a screenshot of what the testcase looks like in the failures (the ones I glanced at, at least).  There's a vertical bar (a cursor/caret?) at the left edge.

The testcase sets `document.designMode` to "on"  and then `off`, with different text coloring rules applying for each state.

The fact that the testcase renders green (as shown in this screenshot) is an indication that we successfully got back to`designMode` of `off`.  But the vertical-bar is only supposed to show up when `designMode` is `on`.  It's quite unexpected that we would ever paint a green vertical bar here, I think.
