Dev server serves wrong page when using query parameters without extension

[kixelated]

🐛 bug report

The dev server serves the wrong page when both:

• no extension is provided
• query parameters are used

🎛 Configuration (.babelrc, package.json, cli command)

{
  	"source": [
		"index.html",
		"publish.html",
	],
}

🤔 Expected Behavior

• /publish returns publish.html
• /publish?foo=bar returns pubish.html
• /publish.html?foo=bar returns publish.html

😯 Current Behavior

• /publish correctly returns publish.html
• /publish?foo=bar incorrectly returns index.html
• /publish.html?foo=bar correctly returns publish.html

💻 Code Sample

Reproducible on this commit.
