In viewports widths of <880px, the variant banner shows a scrollbar in the first column and parts of the bank account details may be hidden. This affects only ~1.5% of impressions, but we should prevent banner display in these cases.

Acceptance Criteria

• If the viewport width is less than 880 pixels wide
  • the control and variant banner are not displayed.
  • a WMDEBannerSizeIssue is logged.
