T249744 was the original bug which morphed into this bug after 2b8c59589d26207b40b7957e074d1af25f86d3ba landed and was deployed.

This bug has existed in Parsoid/JS as well ... except that it reports the error and blithely carries along with the rest of the processing.

[subbu@earth:~/work/wmf/parsoid] node bin/parse.js --pageName 'Page:Popular_Science_Monthly_Volume_20.djvu/414' --domain en.wikisource.org --oldid 8069396 < /dev/null > /dev/null
[error/extension][enwikisource/Page:Popular_Science_Monthly_Volume_20.djvu/414?oldid=8069396] Error obj.k.toLowerCase is not a function  parsing extension token ....

Well, at least we now know that this is not a JS -> PHP porting or a Extension API refactoring bug. Just an old porting bug porting Poem to work with Parsoid.
