Looking at a page like https://issue-159--delta--hlxsites.hlx.page/us/en/skymiles/how-to-earn-miles/earn-with-delta, I think the solution doesn't really work well.

And looking at https://issue-159--delta--hlxsites.hlx.page/us/en/skymiles/medallion-program/how-to-qualify which was the page with the issue, I think we should rather fix the CSS for:

.skymiles .default-content-wrapper p:first-child:has(strong) {
  margin-top: 3rem;
}
