This is a real bug, and after some digging, I've uncovered the root cause.  You can find an actually reduced testcase at the end of this comment.

The bug is that the min-width of a colspanning cell constrains the width of normal cells in the same column, rather than constraining the width of the *set* of columns that the cell spans across.

Firefox correctly makes the colspan only constrain the set of columns.

Reduced testcase:

<!DOCTYPE html>
<table width="100%">
  <tr>
      <td width=100>My size is weird!</td>
      <td width=100%></td>
  </tr>
  <tr>
    <td colspan="2">
      <pre>I'm some long non-breaking text in a colspanning cell, and I stretch the first cell in the previous row!</pre>
    </td>
  </tr>
</table>
<style>
td { border: thin solid gray; }
</style>
