Automatic update from web-platform-tests Scrollable table cell child with % height may affect table height. There's a rule in the table spec (which is marked as not ready for implementation) [1] that percentage block-size children of a table cell do not contribute to the block-size of the cell or table, if said child has overflow 'auto' or 'scroll'. However, this shouldn't be applied if the block-size of the table cell is unrestricted (auto), since the child in question may very well be the only child of the cell, and the cell may be the only child of its row, in which case we'd end up with zero block-size for the content. There's similar code in the legacy engine, in LayoutBox::ContainingBlockLogicalHeightForPercentageResolution(). Just like in legacy, we'll just check the block-size of the cell and the table, and ignore e.g. min-block-size.
