When the tab is the current tab, the text is bold and displayed in a different font. When the tab is not the current tab, it appears correctly. If the current tab is not the right-most tab, the title can spill over onto tabs to the right of it. The URL is a test-case I created. I first noticed this at http://www.dougscripts.com/ Reproducible: Always Steps to Reproduce: 1. Visit the above URL in a tab. Actual Results: When viewed as the current tab, it will display incorrectly. Expected Results: When viewed as the current tab, it should display correctly, using the proper font and not spill over onto other tabs.

Not sure what you mean, but I see partially another font in that tab (also inactive) when there is a unicode character in that line. That's bug 332649 I think.

Should have included a screenshot before. Here's what I'm talking about.

This may be same as bug 347011.

Really? Bug 347011 looks different to me. At least, the symptoms are different. Are the tab titles drawn with 10px Verdana? I don't see anything about bold text or focus in that bug, either.
