office-ui-fabric-react v6.111.0

Minor changes

• The Dropdown component will now only include an aria-labelled-by attribute when there is no provided ariaLabel prop. This means that the component will honor provided ariaLabels and create markup such that screen readers will read the aria label and not the regular label. (commit by ConorWuertz, pr #7292)

Patches

• DetailsList: Prevent override of column cell border while dragging (commit by arkogupta, pr #7211)
• spellCheck defaults to false in BasePicker (commit by yumikohey, pr #7301)
