On Windows, clicking on an image element in RichText without a URL causes File Explorer to open

cocos2d-x/cocos/ui/UIRichText.cpp

Line 1762 in 2ac747c

imageRenderer->addComponent(ListenerComponent::create(imageRenderer,

   auto rich_text = cocos2d::ui::RichText::initWithXML(
        "This is a tiny image of a hand: <img src='combined_hand.png' width='36' height='36' type='1'/>");
   ... add to parent etc

then click on the image, and the OS will try to open the URL, but since it's blank, it defaults to the root filesystem path I think.

On my fork I've just added an 'if URL length' check in this one spot, but I haven't tried much more. Seems like there's a few spots the ListenerComponent is bound to the image element but I haven't ran into it yet.

       if (url.length() > 0) {
        imageRenderer->addComponent(ListenerComponent::create(imageRenderer,
                                                              url,
                                                              std::bind(&RichText::openUrl, this, std::placeholders::_1)));
        }
