While reviewing the attachment view page PDF files names appears in the gray boarder

PDF files are not being rendered properly on the Attachment View Page.

Steps to Reproduce:

1. Create a Page
2. Then attach a PDF file (the size of the name does not matter)
3. Navigate to Tools > Attachments
4. Observe that there will be part of the text over the gray boarder (Please refer to the attachment).

This does not happens with the documentation theme.

I tested with latest versions of Chrome, FireFox and IE and I was able to reproduce the issue.
