mossop - I saw you did a review on bug 1148192. Do you know who can investigate a regression in pdf.js? loic - We picked up a new version of pdf.js for 40 (bug 1157827). Can you confirm that 40, 41, and 42 are all affected?

Yes, all three are affected, the next updates of pdf.js have not fixed this regression.

Brendan maybe? I only review the browser integration pieces.

Looks like we will ship 40 with this bug. However, it seems that we will have a fix in time for 41.
