Bump loofah from 2.18.0 to 2.21.3

[dependabot]

Bumps loofah from 2.18.0 to 2.21.3.

Release notes

Sourced from loofah's releases.

2.21.3 / 2023-05-15

• Quash "instance variable not initialized" warning in Ruby < 3.0. [#268] (Thanks, @​dharamgollapudi!)

2.21.2 / 2023-05-11

Dependencies

• Update the dependency on Nokogiri to be >= 1.12.0. The dependency in 2.21.0 and 2.21.1 was left at >= 1.5.9 but versions before 1.12 would result in a NameError exception. [#266]

2.21.1 / 2023-05-10

Fixed

• Don't define HTML5::Document and HTML5::DocumentFragment when Nokogiri is < 1.14. In 2.21.0 these classes were defined whenever Nokogiri::HTML5 was defined, but Nokogiri v1.12 and v1.13 do not support Loofah subclassing properly.

2.21.0 / 2023-05-10

HTML5 Support

Classes Loofah::HTML5::Document and Loofah::HTML5::DocumentFragment are introduced, along with helper methods:

• Loofah.html5_document
• Loofah.html5_fragment
• Loofah.scrub_html5_document
• Loofah.scrub_html5_fragment

These classes and methods use Nokogiri's HTML5 parser to ensure modern web standards are used.

⚠ HTML5 functionality is only available with Nokogiri v1.14.0 and higher.

⚠ HTML5 functionality is not available for JRuby. Please see this upstream Nokogiri issue if you're interested in helping implement and support HTML5 support.

Loofah::HTML4 module and namespace

Loofah::HTML has been renamed to Loofah::HTML4, and Loofah::HTML is aliased to preserve backwards-compatibility. Nokogiri::HTML and Nokogiri::HTML4 parse methods still use libxml2's (or NekoHTML's) HTML4 parser.

Take special note that if you rely on the class name of an object in your code, objects will now report a class of Loofah::HTML4::Foo where they previously reported Loofah::HTML::Foo. Instead of relying on the string returned by Object#class, prefer Class#=== or Object#is_a? or Object#instance_of?.

Future releases of Nokogiri may deprecate HTML classes and methods or otherwise change this behavior, so please start using HTML4 in place of HTML.

Official support for JRuby

This version introduces official support for JRuby. Previously, the test suite had never been green due to differences in behavior in the underlying HTML parser used by Nokogiri. We've updated the test suite to accommodate those differences, and have added JRuby to the CI suite.
