Treesitter: Injections lose highlights with 'spell' enabled after scrolling to the right

[Sam-programs]

Problem

Injections lose highlights with 'spell' enabled after scrolling to the right.

Steps to reproduce

nvim --clean -u minimal.lua file.lua

-- minimal.lua
vim.schedule(function()
    vim.treesitter.start(0, "lua")
    vim.o.spell = true
    vim.o.columns = 48
    vim.cmd("set nowrap") -- i don't know why vim.o errors
    vim.api.nvim_input(":5<cr>w")
end)

-- file.lua
function some_function_which_is_needed_to_repro() end

vim.cmd("ls")
-- look at "ls" and
-- press_w_here________________________________ a

Expected behavior

Injections keep their highlights after scrolling to the right.

Neovim version (nvim -v)

1 Day old master. 4990701

Vim (not Nvim) behaves the same?

No treesitter in vim.

:Inspect on "ls" shows the entry for @keyword highlight from the injection, which means that treesitter is working correctly. So probably the problem is in redrawing.
