Bug 301470 – git-webkit log --hash seems very broken

• Component: Tools / Tests
• Status: NEW

[Sam Sneddon [:gsnedders]]

As of 224689d07870, 301906@main, almost any attempt I make at using `git-webkit log --hash` just seems very broken:

Example 1:

```
% ./Tools/Scripts/git-webkit log --hash -n1 224689d07870fdadc75b7b0fbbff9c935237daac

    [WPE] Fix build after 301229

    WPE didn't have the WebExtensions code enabled. Enabling it
    reveals many bugs that assumed Gtk would always be present.
    We can move a lot of code to GTK specific files and leave non-GTK parts
    available for WPE.
    
    This also disables the action-parsing test on WPE, since that
    test creates a PNG image and WPE doesn't have any libraries that
    support doing that.

        AX: YouTube embed elements should create AX elements based on their node

        Accessibility elements are (in most cases) based off of the renderer. For
        YouTube embed elements, due to some special-casing, the Embed parent and
        the shadow dom child share the same renderer (see
        HTMLPlugInElement::createElementRenderer). This breaks accessibility
        assumptions. Instead, add a rare data field on render objects to indicate
        if it is a youtube embed replacement, and if so, default to using its
        renderer.
