<table style="writing-mode: vertical-rl; border-spacing: 0">
<tr><td id="cell" style="width: 200px; height: 100px; padding: 0"></td></tr>
</table>
<script>
document.body.offsetTop;
cell.style.width = "100px";
</script>
The cell should shrink to 100px wide. Instead it kept its 200px width.
Let's compare the cell's size along the row's block axis.
