Forcer <summary> à se comporter comme display: inline au lieu de inline-block

Question

Je voudrais utiliser les balises <details>/ <summary>pour les popups CSS purs, mais <summary>se comporte comme un bloc en ligne et je ne peux pas le changer en inline.

Existe-t-il un moyen de forcer <summary>à se comporter comme display: inline au lieu de inline-block?

<!DOCTYPE html>
<html>
  <head>
    <style>

      summary {
        color: red;
      }
      
      summary::-webkit-details-marker {
        display: none;
      }

      details, summary {
        display: inline;
        /* hyphens: manual;/ */
        /* word-break: break-all; */
        /* overflow-wrap: anywhere; */
        /* white-space: unset; */
      }

      .mimic {
        color: darkseagreen;
        display: inline-block;
      }

    </style>
  </head>
  <body>
    <span>
      I would like to use the &ltdetails&gt / &ltsummary&gt tags for
      pure CSS popups,
      <details>
        <summary>
            but &ltsummary&gt behaves as inline-block
        </summary>
        (I'm fine with &ltdetails&gt)
      </details>
      and I cannot change it to inline. Is there any way to force &ltsummary&gt
      to behave as display:inline instead of inline-block?

        Just start to play with the width of the viewport...

display: contents; peut le faire mais il se comportera étrangement:

summary {
  color: red;
}

summary::-webkit-details-marker {
  display: none;
}

details,
summary {
  display: contents;
  /* hyphens: manual;/ */
  /* word-break: break-all; */
  /* overflow-wrap: anywhere; */
  /* white-space: unset; */
}

.mimic {
  color: darkseagreen;
  display: inline-block;
}

<span>
