goimports will not automatically delete duplicate imports at certain case

[andyafter]

Hey there I am working on go language version 1.12 darwin/amd64. I have saved my go import as the following:

import (
    "context"
    
    "some/package/aaa"

    "another/package"
    "some/package/aaa"
)

And in this case, only in this case, goimports will not be deleting duplicate imports automatically. I tried with terminal command, emacs and vscode.

Please see @rsc's comment here #26846 (comment).

We intentionally leave this to local custom - gofmt and goimports will never move imports across blank lines in the import block. So if I want path with the others, I can do that, and gofmt/goimports respect that. And if you want all your renamed imports together, you can do that, and gofmt/goimports respect that too.

i.e. imports separated by blank lines are considered separate and that is intentional. Hence gofmt/goimports will not dedup entries beyond a single import group.

Damn it I thought I finally got something
