Can you remove this? It seems unused now.

Is there anything ensuring the PluginInfoProviders are kept alive for this loop? If they are tied to the page's lifetime, do we really need the two loops?

> Source/WebCore/plugins/PluginInfoProvider.cpp:57
> +    for (auto& frame : framesNeedingReload)
> +        frame->loader().reload();

For a specific page, is there any reason to reload a frame that is a child of a frame that has already been reloaded in this loop? For instance, if the main frame is reloaded, what is the value of reloading any subframes?

[Sam Weinig]

Oh, as always, is this testable?

Patch landed with this unused vector still there. Should remove it!
