Can't download attachments from Monograph pages

[ikesler]

Steps to reproduce

1. Create a note
2. Add a file attachment to the note
3. Publish the note
4. Open publish URL in browser

Expected result

Attachment is listed at the bottom of the page. Clicking it should allow downloading the file.

Actual result

Attachment is listed but there is no way to download it. Clicking the attachment shows a floating button (see the screenshot) which looks like a "Download" one but clicking it does absolutely nothing.

Also, this button shows a weird tooltip: ueLv9s. There is also a related warning in the console:

Uncompiled message detected! Message:
> ueLv9s
That means you use raw catalog or your catalog doesn't have a translation for the message and fallback was used.
ICU features such as interpolation and plurals will not work properly for that message. 

Please compile your catalog first.
