Can do this more efficiently like so:

    auto host = m_document->topDocument().url().host();
    return startsWithLettersIgnoringASCIICase(host, "mail.") && topPrivatelyControlledDomain(host.toString()).startsWith("yahoo.");

Also, I think we should write an isYahooMail helper function so we can share this logic with Quirks::shouldAvoidPastingImagesAsWebContent. Also, that uses a data member to cache the result. Should we be doing that here too? Or sharing a single one?

There's a bit of missing context here: that the mobile site doesn't work well with mouse events in a particular case.

> Source/WebKit/WebProcess/WebCoreSupport/WebFrameLoaderClient.cpp:570

> +    if (mouseEventPolicy == MouseEventPolicy::Default && document->quirks().shouldSynthesizeTouchEvents())
> +        mouseEventPolicy = MouseEventPolicy::SynthesizeTouchEvents;
> +#endif

Is there a reason we can't tuck this away in the DocumentLoader mouseEventPolicy() getter instead?

A shared function is a good idea I'll do that.

As far as saving this to a variable, I was thinking that this is only called during top-level/frame navigations so it wouldn't happen that often, but perhaps caching it is a good idea.

I was trying to follow what `DocumentLoader::simulatedMouseEventsDispatchPolicy` does, but I think your idea is probably cleaner.  I'll change it.
