BUG: height of comment with attachment hides Add Comment button

What is the challenge?

• When adding a document to a comment on a Feature, the Add Comment button is not visible without scrolling.

• The user is not prompted to inform them they haven't clicked Add Comment when they click away from the Feature side panel, which auto-closes the side panel.

What is the impact?

• This has caused a few of our users to close the side panel thinking they had posted their comment with the attachment when it wasn't actually saved. As a result, the other users who are waiting for the attachment to be added, are never notified since the comment was never actually added.

Describe your idea.

• Ensure the Add Comment button is always visible, either by putting it above the tile showing the attached file (since the file is shown inline in the comment anyway) or by ensuring the bottom whitespace is fully used so the Add Button isn't hidden below an invisible fold.

• While this can be solved by the users just remembering to scroll and click the hidden button, this seems like a lightweight UI fix that would make the UI more intuitive, particularly for infrequent users who wouldn't know to scroll to find the Add Comment button.
