I'm using default everything and when doing some thing like this promptHelp is not replaced by the default prompt text :
this.$dialog
.prompt({
title: "some title",
body: "some body <a href='url'>link</a>",
promptHelp: "No matter what i put here it is not displayed"
},{ html: true })
.then((dialog)=>{console.log(dialog.data)})
.catch(()=>{})
