Go to definition takes me to wrong line; wrong tokens highlighted on hover

Created by: dadlerj

Filing on web, even though this has to do with codeintel, because it seems like it's affecting non-codeintel extensions as well (e.g. token highlights)

Repro:

• Hover over this token: https://sourcegraph.com/github.com/sourcegraph/sourcegraph@599f414/-/blob/enterprise/cmd/frontend/internal/licensing/licensing.go#L69:18
• Note that the Lock token in mu.Lock() on line 88 is highlighted
• Click go to definition
• Land on the Lock token on line 88
