legend: fixes Firefox/baron scroll bug

create annotation on non-editable dashboard

scroll: temporary fix for double scrollbar issue

Compensates for Firefox scrollbar calculation error in the baron framework.
Offsetwidth and clientwidth are used to find the width of the scrollbar. In
the legend these differ by 9px and cause the scroll div to grow by 9px for
every refresh. This fix compensates with a negative margin-right in that
case.

Fixes #11830

If #11939 is not merged in the patch release, then
this is a temporary fix for 5.1.3. It sets overflow to
hidden for larger screens and keeps the overflow set to
auto for mobiles and tablets.

Fixes #11937
