This also is broken with the LocName tag, which did the same thing.
/give @p potato{display:{LocName:"Not Italic Potato"}}
LocName
was removed entirely

Can also confirm. Bold works fine.
According to the wiki, italic normally defaults to false in translatable text components. However, renamed items default to having italicized names. I would therefore guess that the conflict is somehow causing the value of "italic" to be ignored.
Not fixed in 18w02a

Confirmed for 18w11a.

Confirmed bug in 18w15a

Even if the name does not appear in italic in the inventory, it still appear in italic when selecting the slot of the item in the hotbar (in 18w19b)

It’s marked as fixed for today’s snapshot.
Can confirm the fix in 20a.
Confirmed for 18w01a.
