Comment in shared review goes blank when clicked in
I'm using Document Cloud to conduct shared reviews. When I click into a comment in the comment pane to find where in the document it applies, the entire comment will go blank, although the comment field/container remains in place. If I click on the comment icon in the document, the comment also goes blank. This is making it difficult to determine where in the document a comment applies or what the reviewer is telling me, depending on whether I'm clicking in the comment (to find where it applies) or clicking the icon (to find out what the reviewer is telling me).
