Another possible test
data:text/html,<!doctype html><html><div style="border: 1px solid black; width: 5ch;" contenteditable>AAAAAAA</div>

This is done here. 
https://github.com/WebKit/WebKit/blob/14129e759715bb8535b8b7a7512860f79fba2993/Source/WebCore/html/HTMLElement.cpp#L201-L208

        case ContentEditableType::True:
            addPropertyToPresentationalHintStyle(style, CSSPropertyWordWrap, CSSValueBreakWord);
            addPropertyToPresentationalHintStyle(style, CSSPropertyWebkitNbspMode, CSSValueSpace);
            addPropertyToPresentationalHintStyle(style, CSSPropertyLineBreak, CSSValueAfterWhiteSpace);
#if PLATFORM(IOS_FAMILY)
            addPropertyToPresentationalHintStyle(style, CSSPropertyWebkitTextSizeAdjust, CSSValueNone);
#endif
            break;

It seems to have been there for a long time. moved from Frame.cpp into HTMLElementImpl.cpp

It was carried away from on Oct 15, 2004

In Gecko the [contenteditable] CSS is available in a dedicated CSS

The discussion on the CSS mailing-list never reached a conclusion. I filed a bug on Firefox.
