Inlinification (such as what happens to the block-level contents of a run-in or ruby annotation) currently doesn't affect the display of layout-internal types like table-row: for these boxes no computed value display alteration happens, and anonymous box fixup will wrap them accordingly. Blockification instead converts the display value to block (so no anonymous box fixup happens, and also any further structure inside it is disrupted by the conversion to block). Is there a reason to do one vs the other here?
