Filepicker content is displayed out of the filepicker when the user zooms out the browser window.

When we zoom out the browser ('Ctrl' + '-'), then the filepicker content is displayed out of the filepicker.

If you change the content size (.file-picker .fp-repo-items) for 1 less pixel, then it fixes it. Also note that the issue doesn't appear to each unzooming level, only some levels are affected.
