Save website to "mht" format

[Kita2345]

Is your feature request related to a problem? Please describe. Can you add the option to save website as "mht" format?

I don't like to save as pdf. no different from firefox. the thing that I don't like is the image-based snippet of screenshots

Although "mht" is archive based. but the website that is saved still has the original element

Thanks

I'm guessing this can be done using WebView.saveWebArchive.
