That's not going to work. There's some scenarios where file will is undefined and it will crash:

• In the modal navigate to a folder with 50+ children
• Start editing a file or a folder in the editor
• Navigate to a different page

That's still not going to work. The insert modal allows you to edit folders and it needs to know it's a folder to suppress the "Details" button. This PR introduces the following bug.

• In the "Insert Image" modal, navigate to a directory with 50+ folders/files
• Edit a folder.
• Use the pagination to access more files/folder.

Expected result: the editor is still present allowing you to edit the folder and an the "Details" button doesn't show.
Actual result: The "Details" button start showing
