3. import file from another js/svelte file like `src
4. run build

Anything else?

This was working in 3.0.13

If you change the above subfolder name from .test to _test then everything works.

This is a regression caused by #2912 . Checking to see what the best way to fix.

@FredKSchott It doesn't appear that excluding . folders was done intentionally as part of that issue. If so I can fix this by removing that code.

[FredKSchott]

Good catch, we thought that this was already the default behavior since glob excludes dotfiles by default. But it looks like .dotfile/* directories were actually still included by default.

We were just trying to match existing behavior using the new fdir library, so the intention here was zero breaking changes. @matthewp if you can see how to fix, lets go ahead and do that.
