Popup menu alignment issue

[gi1242]

If you use any completion menu that has extra info (e.g. icons or images), then the alignment of items in the menu gets messed up, and the menu becomes too wide. I'm attaching two screenshots, one showing the alignment issues in neovim-qt, and the other showing everything working in Goneovim:
