How to disable the automatic addition of "www." and ".com" between the hostname when entering the address bar

When you search in the address bar, Google Chrome automatically adds "www." and ".com" between the search word. I do not know the reproducibility conditions, but in many cases the problem occurs through the process below:

• Focus on the address bar and select any part in the address bar.
  • domain
  • colon
  • whole search string
• In condition 1 completed state, enter return when the address bar is not separated by a space.

Example (address bar line -> address bar line after entering return code):

• localhost -> www.localhost.com 127.0.0.1 -> www.127.0.0.1.com
• chrome: // o -> chrome: //www.about.com

• Foo: 8080 -> www.foo.com: 8080

• foo.com → foo.com

• foo.jp -> foo.jp
• foo bar -> foo bar

In Firefox, I was looking for a solution that toggles the "browser.fixup.alternate.enabled" variable to false, but I don't know how to solve this in Google Chrome.

I've already tried: - Disable "Use a prediction service to help fill in the search and URLs typed in the address bar". - Clear the cache by accessing "chrome: // net-internals / # dns". - I confirmed that I reproduce even in the secret window.

How should I do to resolve this condition?
