Zooming on a multi-page PDF in the iOS app sometimes brings you back to the first page

Issue Summary

When opening a multi page PDF document on an iPad and zooming into things, it may take the user back to page 1 of the document, so then they have to scroll back to the part I need but it keeps happening.

Currently, have only seen reports on iPad.

Steps to Reproduce

1. Attach a multi-page PDF file to a card
2. Open the PDF attachment
3. Scroll down to page 2 or beyond
4. Pinch to zoom in

Expected Results

Zooms in on the focused area of the document

Actual Results

Occassionally reverts user back to the first page of the document

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
