Description zalan 2020-10-12 18:00:50 PDT 
<div class="flexbox" style="width: 4em; height: 4em; background: silver">
  <p id="ok" style="margin: auto; font-family: Ahem">OK</p>
</div>

and

<div style="width: 4em; height: 4em; background: silver">
  <table style="width: 100%; height: 100%;"><tr><td style="text-align: center; font-family: Ahem;">OK</td></tr></table>
</div>

are not compatible when it comes to inline content vertical positioning due to the different rounding strategies (at block level).
This test fails for example when font-size is set to 20px.
