invalid SVG file uploaded breaks media library

Hi,

we have accidentally uploaded non-valid SVG file, which is actually HTML, into the WordPress media library. Media library grid view (AJAX variant) is broken since then, AJAX call “query-attachments” returns error, and there are PHP warnings in PHP error log:
