Reviewed again but now tests look correct. Sorry if this was a false alarm in advance.

Hi @kojiishi

Now I have reviewed these tests. But it will take a time to remember my previous work...
Please give me some time.

Hello Koji and Hajime :)
It has been a long time since we talk. I hope you are both fine and doing well.

When reviewing the original test back in 2015:
http://hg.csswg.org/test/file/889e2828b06a/css-writing-modes-3/inline-block-alignment-007.xht
there was no .ignore { color: silver; } rule
but I have no objection about the .ignore rule and gray box.

I see nothing wrong with those 5 tests and 3 reference files.

Hello @kojiishi

I think that these tests are correct.

These tests are for 'vertical-lr'.
So a rendering of these tests should be equal to flipped of tests for 'vertical-rl' (e.g. external/wpt/css/css-writing-modes/inline-block-alignment-002.xht).

Reviewed again but now tests look correct.

Do you think that these tests are correct now?

Thank you for taking a look, Hajime and Gerard. I think this was a false alarm, sorry for the noise.

I think my memory is coming back -- @fantasai and I reviewed them because there were no impls that pass, and concluded tests are correct. That might be why we didn't take any actions after the review.

there were no impls that pass
