reactjs - React Quill Matchers are not applying to Headers -


i've made custom attributor classes highlighting whole lines, i've run issue clipboard matchers.

using quill toolbar buttons can toggle attributors on line, when updating contents db (which uses dangerouslypastehtml()), <h1> elements have attributor classes stripped of them.

i think has matches , fact both attributor , headers block scoped, can't figure out.

custom attributor:

export default class diffhighlightattributor extends parchment.attributor.class {     add(node, value) {         if (!this.canadd(node, value)) return false;         this.remove(node);         node.classlist.add(`diff-${this.keyname}`);         return true;     }      remove(node) {         let matches = match(node, this.keyname);         matches.foreach(function(name) {             node.classlist.remove(name);         });         if (node.classlist.length === 0) {             node.removeattribute('class');         }     } }

instantiating , registering attributors:

const parchment = quill.import('parchment'); const delta = quill.import('delta');  const diffremoveattributor = new diffhighlightattributor('highlight_removed', 'highlight_removed', { scope: parchment.scope.block }); const diffaddattributor = new diffhighlightattributor('highlight_added', 'highlight_added', { scope: parchment.scope.block });  quill.register(diffremoveattributor, true); quill.register(diffaddattributor, true);`

configuring , implementing react components:

this.formats = [         'header', 'font', 'size',         'bold', 'italic', 'underline', 'strike', 'blockquote',         'list', 'bullet', 'indent',         'link', 'image', 'color',         'highlight_added', 'highlight_removed' ];  this.modules = {     toolbar: {         container: `#toolbar${this.id}`     },     clipboard: {         matchers: [             ['.diff-highlight_added', (node, delta) => {                 return delta.compose(new delta().retain(delta.length(), { highlight_added: true }));             }],             ['.diff-highlight_removed', (node, delta) => {                 return delta.compose(new delta().retain(delta.length(), { highlight_removed: true }));             }]         ]     } };  ...  <reactquill      ref='richeditor'     onchange={this.handleinput}      formats={this.formats}     modules={this.modules}     value={this.state.value}     theme={'snow'} >
