Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:69.0) Gecko/20100101 Firefox/69.0

Steps to reproduce:

  1. Create an XML document on the filesystem. For example, I created a file named “x123.xml” and placed the following content in it:

<?xml version="1.0"?>
<x>
</x>

  1. View the file in Firefox. It will show a message about the content being unstyled and say it is showing the tree.
  2. Open DOM Inspector.
  3. Use DOM Inspector to add an attribute to the root element. For example, <x foo="bar"></x>

Actual results:

The display of the document tree went blank.

Expected results:

The document tree display should show the changed document.

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko/20100101 Firefox/70.0

I can confirm this issue is reproducible on the latest Firefox release, Firefox 69 beta 4 and on the latest Nightly 70.0a1 (on Windows 10, Ubuntu 18.04 and Mac OS X 10.14).

I believe this is because we listen for mutation events to add changes to the markup view and they don't work as expected inside XML documents.
