x/tools/gopls: incorrectly suggests internal/singleflight completion #64083
Description
Reported from @seankhliao in slack: gopls reported internal/singleflight (from std) as a completion candidate, while not working in std.
Though related to unimported completion of standard library candidates, I think this is distinct from #63767. Specifically, I am suspicious of the 'fast path' unimported completion which looks at packages already in the import graph:

@seankhliao can you go list -deps ./... | grep singleflight to confirm that this package is in your import graph?
