The flexbox spec now contains the following Note: # CSS 2.1 did not define the baseline of block or table boxes. It is # expected that they will be defined consistent with those of table # cells, as follows: # # [...] # # ‘table’ # The inline-axis baseline of a table box is the baseline of its # first row.
