Bug 111061 – Web Inspector: Adding existing key in DOMStorageItemsView leaves it inconsistent state

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

[Vivek Galatage]

Steps:
1. Create some local storage entries. e.g. { "item1": "value1", "item2": "value2", ... }
2. Navigate to Resources panel and localStorage view
3. Using the last row of the grid (creation node), just enter the value to be one of the existing keys [ "key1", "key2" ... ]
4. Press enter

Expected outcome:
Only one entry per key should be shown

Actual Outcome:
Multiple entries are listed

Patch follows.

Please use early returns as extensively as possible. It improves the code readability and makes it [a bit more] error-proof.

if (keyFound) {
    childNode.removeSelf();
    continue;
}

keyFound = true;
childNode.data.value = storageData.newValue;
childNode.refresh();
childNode.select();
childNode.reveal();
this.deleteButton.visible = true;

Sorry for missing this. You can replace "childNode.parent" by "rootNode", right?
