Export->Import WordPress menu bug when image is saved as label

[KestutisIT]

So I use this as "Home" content value:

<img src="http://SITE.com/wp-content/uploads/2016/01/home-icon.png" alt="Home" />

And then I export with:
WordPress -> Tools -> Export -> All

And then I import with this official plugin:
wordpress-importer.0.6.3.zip
( ​https://wordpress.org/plugins/wordpress-importer/ )
And then I see that it was 'Home' text imported (the actual page name).

Another bug is if I leave the field empty, after saving it get gone from Navigation menu at all. While I may want to use CSS for that. And assigning a CSS class to menu item is gone/missing. (or maybe that was from the theme), but I want to have an option to leave a blank element and hook to it's css.
