Steps to reproduce:
Open pdf file in PDF.js and scroll fast to the top. it will show white background between the tool bar of pdf.js
Im assuming this is because, its javascript, so the toolbar just follows the website, and webbrowsers have this thing where you can drag beyond the page, as a kinda padding
In Firefox they manage to turn that feature off for the toolbar but not the page when in pdf mode:
In Safari's build in pdf reader, its turned off for the entire page
If any of thoose are possible that would be great.
Alternatively if it isnt, then if possible change the white to dark color in dark mode
Expected behavior:
toolbar to stay in place
