How to resolve extra blank space when printing in Chrome

When printing from Chrome, my page has extra space between lines - in the middle of a <p>!

The extra space is consistently at the same position on multiple pages, and approx. 80% of a line height.

I cannot debug it, since the CSS print emulation does not have this extra space. Also it prints fine in Firefox and Edge.

Seems similar to this question with no answer: Why am I getting extra line and/or paragraph spacing when printing, despite setting @media print styles?

Based on these, I have tried adding disabling transitions, forcing line-height and unsetting orphans and widows:

@media print {
  * {
        -webkit-transition:none!important;
        -moz-transition:none!important;
        -ms-transition:none!important;
        -o-transition:none!important;
        transition:none!important
  }
  
  h1, p {
      orphans: unset;
      widows: unset;
      line-height: 1.15 !important;
  }
}

Any tips on how to find the root cause? Image of the print emulation HTML etc.
