goyo and shade conflict ends in core dump

[macbuse]

Hi

this is a crosspost from sunjon/Shade.nvim#22

It doesn't surprise me that fails but core dumps :(

---

Behavior : Launching Goyo plugin in a split then switching split causes a core dump of nvim

Terminal error message:

/src/nvim/ui_compositor,c.358: compose_line Assertion until>col failed

Expected Behavior: revert to normal highlighting but without core dump
