Redirected page misses url parameter's value after SingIn

[vmordan]

If an authentication occurs on visiting page reports/component/919412/unsafes/?cmp=624

It opens user Sign in page with URL users/signin/?next=/reports/component/919412/unsafes/%3Fcmp%3D624

And on success login it redirects to page with missed URL parameter value reports/component/919412/unsafes/?cmp
