doc.html(editorcontent, {
          callback: (doc) => {     },
          x: 0,
          y: 0,
          margin: [20,20,20,20],
          width :400,
          windowWidth:420,
          autoPaging: 'text',  //text, slice, false
});

As you can see in the following screenshots the < em > and the < strong > tags as well as < code >< pre > tag are messed up somehow.

autoPaging: slice 👍

Research direction

Start by reproducing the provided HTML with jsPDF's doc.html entry point and autoPaging set to 'text', then compare it with 'slice'. Done means inline em/strong formatting and pre/code block line heights render correctly across page breaks without the reported distortion.
