Hi @Jmzp,

I just created a paragraph with some styling like strong, I took the chapter 3 of the excellent https://www.theepochtimes.com/c-how-the-specter-of-communism-is-ruling-our-world ...choose
the table of content loaded in editorjs is seen as a paragraph which json is
---8<--------------
{
type : 'paragraph',
data : {
text : text:<strong>Introduction</strong><br><strong>1. The Rise of Totalitarian Communism</strong><br>\na. The Soviet Communists\u2019 Rise to Power<br>\nb. The Chinese Communist Party\u2019s Power Grab<br><strong>2. The Brutality of Communist Rule</strong><br>\na. Soviet Communist Atrocities<br>\n\u2013 Killing by Famine<br>\n\u2013 The Gulags: Europe\u2019s First Concentration Camps<br>\n\u2013 The Great Terror Against the Soviet Elite<br>\nb. The CCP\u2019s Deadly Campaigns<br>\n\u2013 The Great Chinese Famine<br>\n\u2013 The Cultural Revolution: Slaughter and Cultural Genocide<br>\n\u2013 Unprecedented Evil: The Persecution of Falun Gong<br><strong>3.

}

As I told you, if make a little change on the paragraph and undo , it is was washing all the tags including strong.
due to the call this.editor.save().then((savedData) => {

Now I fixed it with 4 steps:

1. a patch on editor.js I submitted here codex-team/editor.js#1281 , waiting
   to be approved.
2. I rebuild the editor with ./build helper script
3. in index.js of Undo plugin. lin 81, I set editor.save(true) this time
4. I rebuilt too Undo Plugin

and it works like a charm.
