Bug: Small file preview space in Drive

**Summary**

The file preview space in Drive is small with no way to expand. I have noticed the issue with PDF files — jpg and png seem fine, although I haven’t tried every file type & size.

**Steps to reproduce:**

1. Login to platform
2. Upload a PDF file to Drive
3. Open the preview page for the file

**Actual Result**

File preview space appears very small, hard to see with no way to expand.

**Expected Result**

You should be able to see the full file preview.

Example of the PDF file preview:
