Add picture to list of elements allowed without attributes
This is not a security update!
This is a usability update as some HTML elements are valid without attributes however the default behaviour is to strip these out of an abundance of caution. The picture element https://developer.mozilla.org/en-US/docs/Web/HTML/Element/picture is one such element where it merely changes the browser rendering such that one of the child elements will be rendered.
The picture element was not present in the allowlist when it should have been, and so this release fixes that as per #161 .
Very minor bug fix to remove empty elements without attributes
Thanks to @Gusted for microcosm-cc/bluemonday#151 which fixes a bug that allowed a policy to be defined in a way that input could've allowed an empty and meaningless element to be left in the output when it should not have done so.
This is not a security issue, and the details can be seen in the PR comment.
Updated x/net/html
This is an update of dependencies, specifically it updates the HTML parser within go/net/html.
The update removes a capability, Microsoft style comments that allow browser conditionals no longer works. This is due to a fix on the part of the Go team to prevent XSS within HTML comments, and the commit in question is here https://github.com/golang/net/commit/06994584 . There is no easy to see safe way to restore that functionality without adding more risk to those who .AllowComments() and so I am accepting that this non-standard use of HTML comments is no longer supported.
As part of this version, the older release of v1.0.19 is retracted.
Add SVG inline images, improve RGB color and length matching, fix bug
Add support for the "sandbox" attribute on the "iframe" element
As per microcosm-cc/bluemonday#135@kiwiz has added support to bluemonday that allows the iframe element to correctly declare the security attribute sandbox.
