The Markup Panel will stop displaying nodes after a certain size.

1. Open data:text/html,basic
2. Run the following in a Scratchpad:

let node = document.body;
let div = document.createElement("div");
node.appendChild(div);
node = div;
for (let i = 0; i < 200; i++) {
  div = document.createElement("div");
  node.appendChild(div);
  node = div;
}

3. Open the Inspector and navigate to the last <div>

See Screenshot. Last div is not displayed properly.

FWIW this is still the case in Firefox Nightly 37.0a1 (2014-12-11).

This is still the case now. The HTML parser has a limit to how deep you can go.
There is a thread on dev-platform now that might lead to a solution: https://groups.google.com/forum/#!topic/mozilla.dev.platform/SUknMzK1ZAc
But for now, we're still blocked on this.
