Fixes

Fonts and stylesheets

• Fonts declared inside a frame whose content cannot be read are no longer all removed, which left the text of those frames in a system font
• Replacing a stylesheet element no longer drops the attributes that identify it: id, class, data-* and title are kept. Plain saves lost them on every page with an external stylesheet
• A font-family built with var(), a multi-word family name, or a custom property naming another custom property is now resolved when removing unused fonts
• A font shorthand the parser cannot read, such as font: bold var(--font), no longer counts the fonts it names as unused
• A font value that cannot be resolved no longer switches off font removal for the whole document
• Vendor-prefixed values the browser supports are kept
• Font faces already declared with the same sources are no longer embedded twice
• Circular @import rules no longer make the capture loop until it times out

Page content

• Inline SVG is no longer removed when images are blocked, which deleted charts, icons, gradients and filters
• The constructed stylesheets of a closed shadow root are no longer lost
• The canvas image of a page that was already saved is kept
• A canvas tainted by a cross-origin resource is now reported instead of being dropped silently
• Video posters are stored in a lossy format, and autoplay is dropped from media elements left without a source
• A listener added for adopted stylesheets was never removed and accumulated one per shadow root per save

Filenames

• Every character is kept when replacing the characters a filesystem rejects; a run of them was collapsed, so C++ was saved as C＋
• The ellipsis counts toward the filename length limit

Self-extracting archives

• Self-extracting pages can read the names of the entries they contain. They declare windows-1252, and a non-ASCII character in the inlined ZIP library made every legacy entry name decode to garbage
• Shared copies of duplicate stylesheets no longer keep the addresses of the original page, which left the images they reference missing from the archive
• A stylesheet shared by duplicate <style> elements is stored once instead of twice
• Saving an archive no longer asks the captured site for a ZIP worker three times
• Script resources are named with a .js extension, so a module script saved from a .ts URL is no longer refused when the archive is opened
• The compression of a resource is decided from its content type when there is one
• The SingleFile comment and the canonical link are withheld from a password-protected archive; both carried the page URL in the clear
• The %PDF- header stays within the range PDF readers scan whatever the length of the page doctype
• Extracting the ZIP data from the document is hardened: the data is addressed by an identifier instead of its position, the candidate nodes are checked against the payload, and a failed download falls back to the page data
• An embedded image or PDF the wrapper ladder cannot hide is left out of the file instead of being written unhidden
• Editing a self-extracting archive and saving it again keeps the options it was created with, read from the file itself

Extension API

• An extension whose capture request is refused is now told why on Chromium. It previously received no answer at all and could only time out
