Breaks IdeaVim 2.2

[demming]

For a couple of days I've been observing a weird issue with IdeaVim. On selecting multiple lines in visual mode and yanking them, e.g., Vjy the " register is a blank line ^J, so is the 0 register afterwards. Pasting that register inserts a blank line. But the normal mode yanking of multiple lines does work, e.g., yj or y2k.
