Steps to reproduce the problem

1. Open the attached file with Firefox.

What is the expected behavior?

The first page is rendered in a second or two.

What went wrong?

The first page took 1 minute, 20 seconds to render. Chrome and Acrobat both render the first page in under 2 seconds. It's nothing fancy.

In the browser console, I see 29148 instances of the message:
Warning: Unknown field name, falling back to empty field name.

The message count steadily climbs from 1 to 29148 over the 1 minute, 20 seconds.

The attached file is imperfect because /AcroForm/Fields contains many annotations that are not form annotations.
