Private struct fields from other packages are show in completion suggestion

[dlsniper]

Using the commit 7d7514f (latest at the time of writing).
In the following example the struct private fields are show in the completion suggestion as well as properly highlighted / resolved to the right fields of the original struct.

package main

import "net/http"

func main() {
    tr := &http.Transport{
        wantIdle: false, // this field shouldn't be resolved
        idleCo<cursor> // here there shouldn't be shown any completion values
    }
    _ = tr
}

The error the compiler shows is: unknown http.Transport field 'wantIdle' in struct literal
