Here's a straightforward test scenario:
<html>
<body>
<div style="border:2px solid black; overflow: auto;">
x
</div>
</body>
</html>
Upon rendering, a horizontal scrollbar appears!
I was using FF 3.0.3 for Linux initially and assumed it might be a browser glitch. Upgraded to FF 3.5b4 (the latest release candidate), but the issue persists.
Is this normal behavior? Should I report a bug? Any known workarounds (preferably one that maintains the use of overflow:auto)?
