I think this is only if the unspaced period is in the first term. Having only recently moved to 100% omnibar from URL + Search bars I was momentarily annoyed by what you mention, but I soon realized it really doesn't come up very often because I'll typically use spaced terms and I can remember to put domain names (or inter-period'ed terms) after a first term.
