Static example doesn't work with overriden output dir

[luixo]

Hello,
I cloned static-files example, after that did (from the root):

ls -a
# Results in `. .. .vercel README.md`
mkdir test
mv .vercel test
ls -a
# Results in `. .. README.md`
ls -a test
# Results in `. .. .vercel`

Then I commited that to a repo and created a new project with given framework settings:

It resulted in 404 in deployments and single "static" file in Resources tab.

Without the inner dir hassle it works fine.
I guess it's something with Build Output API, but I couldn't find their repository to complain to.
