Folders side window overlaps media edition fields

Hi,

in the wp_admin, when editing a media on a modal frame launched from inside a content, let’s say after clicking on ‘modifiy’ on an extra custom image field in a Post edition page, the Folders side frame overlaps the media edition fields, like so : https://ibb.co/vLCx4Nr
The smaller the screen, the more the Folders side window overlaps. The only way to access the fields is to largely expand the window (need 27′ monitor).

Do you have any suggestion to make the Folders side window disappears/hide during edition on modal frame ?

Thank you !
