Here's two screenshots to illustrate: http://pasteboard.co/jjkb2DHt3.png http://pasteboard.co/jjkpLanD1.png
After playing around a bit more I noticed two other behaviours sometimes, seemingly at random:
* As described in the first report, except that the cursor will remain after the 'o' instead of jumping to the end of the description
* It will not auto-complete until you type the next character (either 'n' or 'r') to disambiguate - which is the correct behaviour! But this only happened 2/10 times I tried.
