Add icon to child context menu

Question

I want to add an icon to my child context menus. But right now, the chrome extension options for context menu doesnt provide any option to add icon while creating a child menu.
I can add icon to the parent menu using the icon parameter in manifest file. But no option for the child menu.
Any idea how I might achieve this?

A possible workaround is using Unicode Symbols:

Adapted code from this Google sample:

// Create a parent item and two children.
chrome.contextMenus.create({"title": "⛔ Parent", "id": "parent"});
chrome.contextMenus.create(
  {"title": "♣ Child 1", "parentId": "parent", "id": "child1"});
chrome.contextMenus.create(
  {"title": "⚑ Child 2", "parentId": "parent", "id": "child2"});

The submenu "Radio 1" behaves as a radio button, and it's defined with chrome.contextMenus.create({"title": "Radio 1", "type": "radio", "id": "radio1"});

This is just one of many pages of symbols:
