Opera bug with calculating element width

These browser inconsistencies are starting to drive me crazy!

Here's an Opera 7.22 bug I just found:

When calculating an element's width using
document.defaultView.getComputedStyle(element,'').getPropertyValue('width'),
Opera includes the element's padding, which is wrong.

Mozilla does not include the padding.

Upgrade to Opera 7.23 - though I am not sure whether or not you will
still encounter the bug; but there are security issues involved with
7.22 anyway:

In anycase, the above sounds like JavaScript and Opera was never
strong in that department.

Just upgraded. Opera 7.23 still suffers from the bug. :-(

7.22 and 7.23 were pure security fixes, with no changes to the rendering
engine.

Are you sure Opera isn't running in quirks mode? document.compatMode will
tell you.

I have tested with 7.20, see
http://home.arcor.de/martin.honnen/...yleOfWidth.html
and I think delerious is right, it is a bug in Opera.
