Media with a long filename breaks the UI when in a sidebar meta box

[goodguyry]

Description of the bug

If the image selected via Fieldmanager_Media has a long enough filename, the preview container's width is extended. When the field is in the editor sidebar, it's extended width pushes the edit and remove buttons off the edge of the page.

While the edit button's functionality is duplicated in the preview image's click handler, the remove button is unreachable.

Steps To Reproduce

1. Add a Fieldmanager_Media field within an editor sidebar meta box
2. Upload an image with a long name, such as 4d2ea1994d7ffa588d66a6c29a6a5fcew-c2623938235rd-w436_h236_r4_q80.jpg
3. Use the Fieldmanager_Media field to select the newly-uploaded image
4. Observe the edit and remove buttons are pushed out of reach

Additional Information

For now, I've fixed this by adding the following to my project

.fm-file-detail h4 {
    word-break: break-word;
}
