HTML Text String is not rendering

I have two activity passing html data as string  from first activity to second activity.  Second Activity is same as https://github.com/wordpress-mobile/AztecEditor-Android/blob/trunk/app/src/main/kotlin/org/wordpress/aztec/demo/MainActivity.kt . But HTML data is not rendering properly. I cant see any bold text which is part of the html string which is getting passed from the first screen.
