Only number 1 is shown for list items in the numbered list instead of a sequence about roosterjs

Ok, this is because in demo site some content edit features are not enabled by default. Once enabled, this would work.

@juliaroldi I think we should only turn them off for content model demo site.

We fixed it by making the MaintainListChain edit feature asynchronous.
I'm not sure if RoosterJS maintainers want to fix it internally since the legacy editor is being deprecated.

import { ListFeatures } from 'roosterjs-editor-plugins/lib-mjs/plugins/ContentEdit/features/listFeatures';
import { GenericContentEditFeature, PluginKeyboardEvent } from 'roosterjs-editor-types';

// Run maintainListChain edit feature in async to fix the issue "The number of the new line is not increased after typing return"

const { maintainListChain } = ListFeatures;

/**
 * Maintain the list numbers in list chain
 * e.g. we have two lists:
 * 1, 2, 3 and 4, 5, 6
 * Now we delete list item 2, so the first one becomes "1, 2".
 * This edit feature can maintain the list number of the second list to become "3, 4, 5"
 */
export const AsyncMaintainListChain: GenericContentEditFeature<PluginKeyboardEvent> = {
  keys: maintainListChain.keys,
  shouldHandleEvent: maintainListChain.shouldHandleEvent,
  handleEvent: (event, editor) => {
    setTimeout(() => {
      maintainListChain.handleEvent(event, editor);
    }, 50);
  },
};

Hi @haven2world,
I see, thank you very much for sharing the code!

@juliaroldi can you take a look? The recent change should not impact legacy editor, but I remember this should work not too long ago.
