Random error while trying to hop

[bigardone]

Describe the bug
When I have two vertical windows and I try to hop from the one of them, I randomly get the following error.

Error executing Lua callback: ...re/nvim/site/pack/packer/start/hop.nvim/lua/hop/init.lua:110: attempt to get length of a nil value
stack traceback:
        ...re/nvim/site/pack/packer/start/hop.nvim/lua/hop/init.lua:110: in function 'set_unmatched_lines'
        ...re/nvim/site/pack/packer/start/hop.nvim/lua/hop/init.lua:164: in function 'apply_dimming'

This happens after upgrading to the lastest version.
