So, while messing with ctrl-i, I somehow got the forum into a state where the rich text editor bar did not show the italicized-i as selected, but typing would produce text in italics (and cause it to start showing as selected). Okay, reproducer: Type "foo^ibar", backspace over the "bar". When you delete the "b", the italicized-i deselects. But if you type something, it's italics and the italicized-i reselects. To fix this, hit ^i again, and the italicized-i selects; then type something and behold as it turns out not to be in italics and the italicized-i deselects.
