ObjectPage: Avatar as Image causes line-break

[MarcusNotheis]

Rendering an Avatar component as ObjectPage image causes the Header content to break into the next line.
Applying display: inline-flex to the Avatar fixes this issue.

      <ObjectPage title={masterdata.storeName}
                  subTitle={masterdata.storeType}
                  renderHeaderContent={renderHeader}
                  image={<Avatar image={storeFront} shape={AvatarShape.Square} style={{ display: 'inline-flex' }}/>}>
