SingleFile CLI 2.6.3

Core

Updated to single-file-core 1.5.118, which brings:

fonts declared inside a frame are no longer all removed when the frame's content cannot be read. Such a frame is re-parsed from its srcdoc, and a document that is never rendered says nothing about the fonts it draws with, so text in those frames fell back to a system font
replacing a stylesheet element keeps the attributes that identified it: an id a script looks up, a class a selector matches, data-* and title. Plain saves lost them on every page with an external stylesheet
a stylesheet shared by duplicate <style> elements is stored once in an archive, instead of once as the entry the links point at and once in the page
saving an archive no longer asks the captured site for a zip worker three times. The file was never there, and the archive was always written on the main thread anyway
a font-family naming a custom property whose value names another custom property is resolved when removing unused fonts
a font value that cannot be resolved no longer switches off font removal for the whole document. The fonts the page actually rendered decide instead, so a page holding one unreadable value is smaller
vendor-prefixed values the browser supports are kept
