sass mode throwing error on virtual text mode

Describe the bug

Error executing vim.schedule lua callback: ...packer/start/nvim-colorizer.lua/lua/colorizer/buffer.lua:112: col value outside range

To Reproduce

I can trigger the error if I have two scss files, one referencing variables in the other (see screenshot).

Open both files
rename variable $foo: #fefefe; to $oo: #fefefe; and save
go to the other file and :e to reload it
go back to the edited file and change $oo back to $foo and save to trigger error

Expected behavior

no error :)
