Deno hangs on error

Why does Deno hang when XML.parse throws an error?

let text = '<xml><xbrli:xbrl><hi>Hello</hi></xbrli:xbrl></xml>'
import * as XML from "https://deno.land/x/xml/mod.ts"

let parseXml = text => {
  try{
    return XML.parse(text)
  }catch(e){
    return null
  }
};

parseXml(text)
console.log('ok')
try{
  parseXml('fail')
}catch(e){
  console.log(e)
}

let text = '<xml><xbrli:xbrl><hi>Hello</hi></xbrli:xbrl></xml>'
import * as XML from "https://deno.land/x/xml/mod.ts"

let parseXml = text => {
  try{
    return XML.parse(text)
  }catch(e){
    return null
  }
};

parseXml(text)
console.log('ok')
try{
  parseXml('fail')
}catch(e){
  console.log(e)
}

There's already an open issue about that in the lib's repo: https://github.com/lowlighter/xml/issues/28

GitHub

Hangs indefinitely with invalid input · Issue #28 · lowlighter/xml

The following code just hangs forever: import { parse } from 'https://deno.land/x/xml@2.1.1/mod.ts'; parse('A') Or am I doing something wrong here? I'd expect it to throw an error.
