I can’t imagine that CLI updates have anything to do with your situation, as this has been how things work since the dawn of v2. See the “item placement” section of the Item docs. You need to throw one of those attributes on your h2 element in order to have it render.
I search a lot about this topic put no same issue.
but i checked an other browsers such as opera, firefox and Microsoft edge then the h2 tag works fine.
maybe this happens on chrome only but i couldn’t find the solution to fix the issue on chrome and I’m worry that problem facing other users . But any way i will continue with another browser and wish the app work find then.
