Describe the feature

After opening some files from node_modules, in a node.js repo, list of Cmd+P search files don't include the opened files in node_modules because it's git-ignored.

The opened files should be listed when searching for files, even if they're git-ignored.

If applicable, add mockups / screenshots to help present your vision of the feature
