What did you do?

go get a module from VS Code integrated terminal
start to use it from the code
run hover over diagnostics

What did you expect to see?

one diagnostic message about incomplete go.sum and one quick fix for it.

What did you see instead?

multiple, duplicate diagnostics and indistinguishable quick fix entries

Actually, they are not duplicates - each of which is reporting an error for a different package. So, I think this is working as intended technically speaking. I wonder if there is a way to improve presentation if they all share the same quickfix.
