Description distler 2010-10-02 21:46:34 PDT
User-Agent:       Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b7pre) Gecko/20100926 Firefox/ SeaMonkey/2.1b1pre
Build Identifier: 

According to MathML Spec, the mtable 'align' attribute can accept a positive or negative integer, indicating the row of the table, to which the alignment should be applied. 1,2,... indicate the first, second, ... row. -1, -2, ... indicate the last, next-to-last, ... row.

Gecko recognizes positive values, but not negative ones.

See the testcase. 

Reproducible: Always

Actually, negative values are taken into account but wrongly interpreted: -1 is considered the penultimate row, -2 the antepenultimate row etc

Ah.  I was originally going to comment here that dev-doc-needed did not seem to apply to fixing bugs, but I see what was really being asked for was updating developers section of release notes to indicate the bug was fixed.  Perhaps we need a different keyword like dev-relnote-needed to make this more clear.
Comment 8 Bill Gianopoulos [:WG9s] 2011-08-13 08:23:57 PDT
Or perhaps it really should have just had the relnote keyword instead of devdoscs-needed.  Devdocs-needed would seem to imply that the developers wiki needs to be updated.

That's exactly what it means. relnotes are user-facing; dev-doc is developer-facing.
