[css-flexbox] Resolve min-width:auto on table item to min preferred s…

…ize. Edge and Firefox seem to let table flex items use the sizing algorithm of the table extensively, and are therefore generally broken when it comes to flexing tables. We, on the other hand, let the flex sizing algorithm be in charge of sizing tables, so that flexing actually works. However, this causes tables with a specified main size of less than the minimum intrinsic logical width of the table to shrink below their minimum intrinsic logical width, a situation that's generally unwanted for tables. Amend by ignoring the specified main size when resolving min-width:auto on table items. Also ignore max-width/max-height. Just use the preferred minimum logical width.
