Reproducible: Always Steps to Reproduce: 1. Create a bordered table with a shrink-to-fit-contents cell containing a PRE element with one line. 2. Make that line consist of a few TABs followed by text. Actual Results: The table will be too narrow for the text, causing the text to go past the right boundary of the table. Expected Results: The table should be sized to contain the text. There's an obvious workaround: replace TABs in PRE elements with appropriate numbers of SP (U+0020) characters.

The test-case shows correctly in Firefox 3.1b1pre, so this will probably need to be duped to a trunk bug that was fixed.
