We should prefix accessibility bugs with AX: so it's easier to know what aspect of the code their referring to

> Source/WebCore/accessibility/AccessibilityNodeObject.cpp:719
> +    if (isHeading() && getAttribute(aria_levelAttr).toInt() > 0)

You should cache the value of getAttribute rather than call it two times

Is this concern only for the ChangeLog comments? I hadn't been prefixing the bug titles b/c they're all filed in the "Accessibility" component.

Okay, thanks.

My preference is that all Accessibility bugs have AX: in the title. The category of the bug isn't transferred to change logs, commit logs, etc, etc

we should probably do
if (isHeading()) {
    int ariaLevel = getAttribute(aria_levelAttr).toInt();
    if (ariaLevel > 0)
        return ariaLevel;
}

so that every object doesn't have to make that getAttribute call

brackets not needed for a one line if (this will fail style-bot)

> Source/WebCore/accessibility/AccessibilityNodeObject.cpp:743

this extra insertion should probably be removed to reduce churn
