[BUG][EDITOR] Styles without a theme.nxmi still shown in theme selection dropdow

[namida]

This is a case of "title says it all", or at least would be if the "n" at the end wasn't missing due to the title length limit.

I love that the missing "n" meant that an extra 90 characters had to be typed into the OP. Not to mention this reply, which is also relatively pointless.

Fixed in commit 7ef84e4.
