Erratic behavior for 1-key keyboard

[burchill]

I'm interested in making a sandwich case for a keyboard with a single key. Although it seems it can handle a 2-key board fine, it doesn't work for a 1-key board.

The one key input:

[""]

with the following configuration:

results in the following weirdness:
.

But when there are even just two keys, i.e. ["",""], with the same configuration, it results in the perfectly well-formed:

I'm sympathetic to whoever programmed this--this is one of the few situations where somebody (me) actually wants an edge case!

Yes, this is a known issue. I looked into it briefly in the past but I couldn't figure out why it was behaving this way. I can look at it again to see if I can figure out what is going on, but if I can't find the issue in an hour or two I will probably leave it as is since it is such a small edge case.
