getHtmlTagDefinition does not return tag definition if given tag name is constructor, toString, etc... #52224
Description
Which @angular/* package(s) are the source of the bug?
compiler
Is this a regression?
No
Description
getHtmlTagDefinition returns a tag definition for given HTML tag name. If given tag name is unknown, it should return default tag definition new HtmlTagDefinition({canSelfClose: true}).
However, it does not return the default tag definition for some tag names(constructor, toString, etc...), this is because the table of tag definitions is defined as a JavaScript object.
Code example:
import * as ac from "@angular/compiler";
const KNOWN_TAG_DIV = "div";
const UNKNOWN_TAG_FOO = "foo";
const UNKNOWN_TAG_CONSTRUCTOR = "constructor";
const UNKNOWN_TAG_TOSTRING = "toString";
console.log(ac.getHtmlTagDefinition(KNOWN_TAG_DIV));
// HtmlTagDefinition {
// closedByChildren: {},
// closedByParent: false,
// isVoid: false,
// implicitNamespacePrefix: null,
// contentType: 2,
// ignoreFirstLf: false,
// preventNamespaceInheritance: false,
// canSelfClose: false
// }
console.log(ac.getHtmlTagDefinition(UNKNOWN_TAG_FOO));
// HtmlTagDefinition {
// closedByChildren: {},
// closedByParent: false,
// isVoid: false,
// implicitNamespacePrefix: null,
// contentType: 2,
// ignoreFirstLf: false,
// preventNamespaceInheritance: false,
// canSelfClose: true
// }
console.log(ac.getHtmlTagDefinition(UNKNOWN_TAG_CONSTRUCTOR));
// [Function: Object]
console.log(ac.getHtmlTagDefinition(UNKNOWN_TAG_TOSTRING));
// [Function: toString]Please provide a link to a minimal reproduction of the bug
