Dev dependencies was not installed as expected

[edkalina]

I have a project on github https://github.com/edkalina/jsx-decorator-sandbox. It is ejected creater-react-app project with replaced babel config (It doesn't use create-react-app preset). Also it has patched babel packages in dependencies, specified this way:

{
    "@babel/helper-builder-react-jsx": "https://github.com/edkalina/babel#babel-helper-builder-react-jsx",
    "@babel/parser": "https://github.com/edkalina/babel#babel-parser"
}

Locally it works as expected: patched babel packages are installed and project builds correctly. But after importing it to codesandbox I can see parsing errors (looks like original babel was used).

Is it a bug? Is my case unsupported?
