Visual regressions in the upload widget:

- There is too much margin above the modal footer/cancel button
- The modal probably needs some sort of minimum width to avoid things overlapping or overflowing when making it very narrow
- The bin icon is not nicely vertically centred
- The visibility radio buttons are too far to the left
- The autosuggest suggestions have a bold title
- The `Enter name here` field is not nicely vertically centred
