Hi Tom, do you mind having a look at this? Not sure if this component in PDFium is enabled in Chrome.

tsepez, could you please help triage? Thank you!

Doh, sheriffing collision :)

I would have expected https://pdfium-review.googlesource.com/4230 to have taken care of this.  I will see if it still repros following that.

Aha.  The autoroller has been failing for some time and the above hasn't made it into chromium's DEPS yet.  I think this will auto-close when that happens.
