Bump jsdom from 11.6.2 to 15.0.0

[dependabot-preview]

Bumps jsdom from 11.6.2 to 15.0.0.

Changelog

Sourced from jsdom's changelog.

15.0.0

Several potentially-breaking changes, each of them fairly unlikely to actually break anything:

• JSOM.fromFile() now treats .xht files as application/xhtml+xml, the same as it does for .xhtml and .xml. Previously, it would treat them as text/html.
• If the JSDOM constructor's contentType option has a charset parameter, and the first argument to the constructor is a binary data type (e.g. Buffer or ArrayBuffer), then the charset will override any sniffed encoding in the same way as a Content-Type header would in browser scenarios. Previously, the charset parameter was ignored.
• When using the Blob or File constructor with the endings: "native" option, jsdom will now convert line endings to \n on all operating systems, for consistency. Previously, on Windows, it would convert line endings to \r\n.

14.1.0

• Added activation behavior for <a> and <area> elements whose href="" points to a javascript: URL or fragment.
• Added the <datalist> element's options property.
• Added the <input> element's list property.
• Added PageTransitionEvent, and the firing of pageshow events during loading.
• Exposed the External class as a property of window.
• Fixed HTML fragment parsing (via innerHTML and outerHTML) to be spec-compliant. (pmdartus)
• Fixed HTML serialization (e.g. via innerHTML) breaking after setting certain properties to non-string values.
• Fixed how disabling an element would cause its activation behavior to forever be null, even if it were re-enabled.
• Fixed all access to attributes to ignore attributes with namespaces, per the spec.
• Fixed <style>s to no longer apply to documents without a browsing context. This includes fixing a crash that would occur with such styles if they had an [@​import](https://github.com/import) rule.
• Fixed <option>'s label and value properties to return correct values in various edge cases.
• Fixed the load event during document loading to target the Document, not the Window.
• Fixed the pretendToBeVisual option to propagate to child subframes, as well as the main Window. (pyrho)
• Updated the minimum nwsapi version from v2.1.1 to v2.1.3, bringing along a few fixes in our selector engine.

14.0.0

Breaking changes:

• JSDOM.fragment() now creates fragments whose document has no browsing context, i.e. no associated Window. This means the defaultView property will be null, resources will not load, etc.
• JSDOM.fragment(), called with no arguments, now creates a DocumentFragment with no children, instead of with a single child text node whose data was "undefined".

Other changes:

• Fixed a regression in v13.2.0 when calling element.blur() on a focused element.
• Fixed inserting <link> elements into documents with no browsing context to no longer crash if the originating JSDOM was configured to fetch the resource. Now, per spec, <link> elements only attempt to fetch if they are browsing-context connected.
• Fixed \<template> elements to have the correct semantics, of using a separate browsing-context-less document to store its contents. In particular this means resources will not be fetched for elements inside the \<template>, as per spec.

13.2.0

• Added support for MutationObservers! (pmdartus)
• Added support for XML documents loaded in frames and iframes; previously this would error.
• Added the <progress> element's value, max, and position properties.
• Added navigator.plugins and navigator.mimeTypes. (But, they are always empty.)
• Fixed <summary> elements respond to click events by toggling their parent <details>.
• Fixed <summary> elements to be focusable.
• Fixed XML document DOCTYPE parsing to preserve any custom name values.
• Fixed XML documents to default to UTF-8, not windows-1252 like HTML documents do.
• Fixed all events fired by jsdom to have isTrusted set to true.
• Fixed DOMParser-created documents to have their readyState set to "complete".
