STR:

  1. Load the PDF from bug 1056532 comment 1 (https://bugzilla.mozilla.org/attachment.cgi?id=8476619)
  2. Wait for the PDF to be rendered

Expected results:
All contents of the PDF should be rendered right away.

Actual results:
Some items, e.g. the yellow arrow from the graph on the left to the table on the right or label on top of the table on the right, are not rendered until you switch to another tab and then switch back.

Note: this is not reproducible when disabling accelerated canvas.

It was quite painful to find a regression range for this because of the multiple backouts and relandings of bug 1777872, interrupted by other changes to accelerated canvas, but I hope the regressor is correct.
