| +// A document`s browsing context only afffects the look up result of custom element definition
|
| +// https://html.spec.whatwg.org/#look-up-a-custom-element-definition
|
| +// There are two places where we need to look up a custom element definition:
|
| +// 1. creating an element
|
| +// https://dom.spec.whatwg.org/#concept-create-element
|
| +// 2. trying to upgrade an element
|
| +// https://html.spec.whatwg.org/#concept-try-upgrade
|
| +// The previous observation leads to the following behaviours:
|
| +// 1. an element in a document without browsing context should not be upgraded
|
| +// 2. a custom element cannot be created in a document without browsing context
|
| +// 3. an already "defined" custom element should remain "defined" after being inserted
|
| +// into a document without browsing context
