Conditional comments getting removed on latest version

ok now I get it... you were talking about comments in the canvas... Well, to be honest, I don't think you need to care about what you see in the canvas (the important part indeed is in toHTML of the comment component).In any case, you can always try to tweak the view to obtain what you need

It works for me with the latest version https://jsfiddle.net/06L5ng19 Next time, create a reproducible demo before opening a BUG issue, thanks...

Hi @artf , thanks for your time. The issue is happening when adding comments to blocks html. I've updated your code and added some test block with comments inside it: https://jsfiddle.net/orn4jqw7/1/
