Pattern matching in "Find all files" work only for open files?

• VSCode Version: 1.8.1
• OS Version: macOS 10.12.2

Steps to Reproduce:

I have a Go project (https://github.com/ahmetalpbalkan/go-linq) and I am looking for this pattern in the codebase: a '{' followed by two new lines.

I have no open files currently.

I hit Cmd+Shift+F and type regex: \{\n\n, hit the [.*] regex button and then hit return, I get no results:

Suspicious, because I am sure I have some matches.. Then I open a file aggregate.go and I hit Cmd+Shift+F again and return again to perform the exact same search:

Bam! I have matches now, but only from the open file, aggregate.go. Is this a bug?
