File Mount "Content" editor overflows horizontally on long lines, pushing the Save button out of view

When adding or editing a File Mount in the Storage section, pasting content with long unbroken lines (e.g. an HTML file with minified CSS, long @import URLs, or long selector chains) causes the Content code editor field to overflow horizontally instead of wrapping or scrolling internally. This stretches the modal beyond the visible viewport width and pushes the Save button off-screen, making it inaccessible without resizing the window or scrolling awkwardly. This happened while setting the Mount Path to /usr/share/nginx/html/index.html and pasting in an HTML file with minified CSS in the <style> block. Screenshot attached showing the Content field expanding past the modal boundary with the Save button cut off.
