As discussed on the ticket and IRC. Tested this, using the modified complex-dialog visual test, in Chrome, Firefox and IE7. In IE7, the close button disappears below a certain size. The title handling itself works fine.

If we're going with the approach would it make sense to also give the .ui-dialog-title <span> a title attribute so the user can see the full title on hover? Currently it does not have one.

I still think 90% is a better width. At 95% with normal size text, the ellipses can be right up against the close button even at 250px wide. I'm not sure what causes the close button to stop moving in IE7, but when you stop resizing, it does reappear in the correct place, so I think it's fine.

@tjvantoll I've got mixed feeling about adding a title attribute. I wouldn't want it to show up when the text isn't truncated.

[jzaefferer]

Updated to set the width at 90% and use a regular font-size in the complex-dialog visual test. I also agree with Scott on the title attribute - that would be only useful when the text is truncated, for 99% of dialogs it would be just irritating.
