Enabling spellcheck in QTWebEngine

[gerges]

I noticed that in QtWebkit people were able to create spellcheck plugins (such as the one created/used by qupzilla) that use Hunspell and rely on in-built browser highlighting (https://github.com/QupZilla/qtwebkit-plugins/tree/master/src/spellcheck). I also notice that other projects that embed chromium (such as GitHub's Electron) have been able to add in-browser spellcheck highlighting.

https://github.com/atom/electron/blob/master/chromium_src/chrome/renderer/spellchecker/

Is this something on the roadmap for QtWebEngine? Could some of the work Qupzilla and Electron have done be reused here?

Thanks!
