Redux DevTools breaks XML formatting

[henrik242]

Steps to reproduce:

• Disable all add-ons in Firefox
• Open an URL that points to a XML file
• AS EXPECTED: A pretty-printed XML is shown
• Enable the Redux DevTools Add-on
• Open the XML file again
• FAIL: Only the content inside the XML tags are shown

Using Firefox Developer Edition 72.0b6 on macOS 10.15.2

React devtools fixed this issue: facebook/react#17739

Maybe Redux devtools can do it similarly?
