Attachment field setting width in preview pop-up

Hello, please consider setting the width in %, transparency and background color in the pop-up preview window Attachment field.
When viewing a pdf on a 3840*2160 screen, it looks very narrow and hard to read.
When viewing svg with dark elements, they blend into the background.
max-width: 800px

Interesting. Do you mean that max-width: 800px is the problem? Do you think simply removing that style property might improve the sizing issue?

Hello @dmitry-grist I disable this style and see the full width PDF.
