This was a slip-up in the larger clean-up commit in 61da493, where "synchronous" was changed to "in parallel". All browsers implement the synchronous behavior. Fixes #4686. Tests: web-platform-tests/wpt#17439

This creates separate top-level algorithms for each entry point into module script graph fetching in the spec: * Fetch an external module script graph * Fetch an import() module script graph * Fetch a modulepreload module script graph * Fetch an inline module script graph * Fetch a module worker script graph Previously, for several of these entry points, the parts of the spec that implemented them would directly use the lower-level algorithms (such as "fetch a single module script" or "internal module script graph fetching procedure"). Now, those lower-level algorithms are entirely encapsulated within the "Fetching scripts" section. This also introduces a diagram showing the relationship of the algorithms to each other, and rearranges some of the lower-level algorithms for an easier reading flow.

Although the processing model already processed the integrity="" attribute for these, the document conformance requirements were not properly synchronized with the processing model. This commit aligns them.

In the ECMAScript spec, the recently-merged tc39/ecma262#1563 dropped the 'Strict' parameter from the abstract operation FunctionCreate (since its setting can be determined from the 'Body' parameter). This commit makes the corresponding change to HTML's only call to FunctionCreate.

In particular if folks disable support for ShadowRoot and ElementInternals, this will make upgrade an element throw a NotSupportedError so element constructors only run with expected state. Tests: web-platform-tests/wpt#17162.

These were already stated in the category definition, but not properly cross-referenced from the autonomous custom element element definition block. Closes #4634.

In order to append characters to the tag name, it needs to be initialized to the empty string. Also, remove the parenthetical remark (the rest of these were removed in b66ec32).

This makes it behave more similar to its module counterpart.

This commit adds JSON modules as a single default export, with parse errors checked before instantiating the module graph. As infrastructure, this divides the "module script" concept into "JavaScript module scripts" and "JSON module scripts". Most of the spec's existing uses of "module script" become "JavaScript module script". JSON module scripts are fetched in the same way as JavaScript module scripts, e.g. with the "cors" mode and using strict MIME type checking. They use the Synthetic Module Record defined in heycam/webidl#722. Closes #4315. Closes w3c/webcomponents#770.

Since module scripts never execute synchronously, currentScript must already be null here.

This provides the ElementInternals interface, which can be obtained for custom elements via the element.attachInternals() method. For now ElementInternals is empty, but it will gain members in #4383. This also adds the ability for custom elements to set the disabledFeatures static property, to disable element internals and shadow DOM. Some DOM-side infrastructure work there is necessary in whatwg/dom#760. Tests: - web-platform-tests/wpt#15123 - web-platform-tests/wpt#15516 - web-platform-tests/wpt#16853 Fixes w3c/webcomponents#758.

Fixes #4620. This flag prevents reentrancy into the submission algorithm during submit or invalid events. Blink and Gecko implement this for submit only; WebKit implements it for both. The specification chooses WebKit's behavior. Tests: web-platform-tests/wpt#16811

Update the Events Index to include `form` as the elements that is an interesting target. Fixes #4570.

This specifies the layout model of buttons (the button element, the input element in the Button, Reset, Submit states, and the button part of input in the File Upload state). Fixes #1024. Fixes #2948. Fixes #4081. Part of #4082.

Separate the bulk of the algorithm out into internal play steps that can be callable from other specs. This allows specs that doesn't need promises to call the internal steps directly, and also gives a hook that avoids calling the public play() method.
