+  When a table cell has a percentage in the inline axis of the table,
+  it should resolve against zero when computing the column sizes,
+  but once we know the final size of the table, it should re-resolve
+  against that size minus the leading and trailing border spacing.
+  This matches what Blink and Gecko do (WebKit is different).
+
+  Note that Blink and Gecko disagree in case there is a caption:
+  Blink still behaves as per above, while Gecko re-resolves against
+  the sum of column sizes plus the interleaved border spacings.
+  Due to the lack of interoperability, this test doesn't use captions.
