Bug 92104 – Web Inspector: [Regression] Filler row disappears from network log view.

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector (Deprecated)

This happens because http://trac.webkit.org/changeset/123281 broke table's childNodes implementation.

Here is a reduction:

// Initialize table
table = document.createElement("table");
for (var i = 0; i<3;++i) {
    tr = document.createElement("tr");
    td = document.createElement("td");
    tr.appendChild(td);
    table.appendChild(tr);
}

// lastElement value is incorrect (td instead of tr).
lastElement = table.childNodes[table.childNodes.length - 1];
// This code fixes the bug.
for (var i = 0; i<table.childNodes.length;++i)
    var tmp = table.childNodes[i];
// lastElement2 value is correct.
lastElement2 = table.childNodes[table.childNodes.length - 1];
console.log(lastElement.tagName);
console.log(lastElement2.tagName);
console.assert(lastElement === lastElement2); // <-- this assertion fails.

Does this bug reproduce after http://trac.webkit.org/changeset/123359 ?

There was widespread breakage of internal tools at Google after http://trac.webkit.org/changeset/123281, but http://trac.webkit.org/changeset/123359 seems to have fixed them all.

Indeed, it doesn't reproduce on ToT.
