New procedural cosmetic filter operator: :matches-media()

Commit

The argument must be a valid media query as documented on MDN, i.e. what appears between the @media at-rule and the first opening curly bracket (including the parentheses when required).

Best practice:

Use :matches-media() after plain CSS selectors, if any.

Good: example.com###target-1 > .target-2:matches-media((min-width: 800px))

Bad (though this will still work): example.com##:matches-media((min-width: 800px)) #target-1 > .target-2

Fixes:

• Add 0.5s mp3 redirectable resource
• Add queue-related initialization code to AMZN shim script
• Fix dark theme issue in DOM inspector
• Better detect invalid cosmetic filters
• Properly "bleed" 3p rules onto 3p-script/3p-frame cells
• Skip testing context when none present in acis scriptlet
• Ignore auto-repeat events in ctrl keydown event handler
• Fix popup panel for Thunderbird
• Prevent picker from being larger than viewport
• use WebAssembly-1.0 compliant function names (by @rathann)
