The Readability parser currently does not preserve custom element tags such as <my-custom-tag> during the parsing process. These custom tags are stripped out, which can result in the loss of important semantic information and custom function

Desired Feature

Add an option to specify tag names which should be preserved during the parsing.

var article = new Readability(document, {
  tagsToPreserve: ["my-custom-tag", "another-tag"],
}).parse();
