  $(mapId).find('a, button, div[tabindex], iframe').each(function(index, item) {
    item.setAttribute('tabindex', -1)
  })
}

function enableGoogleMapsTab(mapId) {
  $(mapId).find('a, button, iframe').each(function(index, item) {
    item.removeAttribute('tabindex')
  })
  $(mapId).find('div [tabindex]').each(function(index, item) {
    item.setAttribute('tabindex', '0')
  })
}
