Can't shrink selection manually

[xzbdmw]

I have this custom keymap

keymap("x", "<bs>", function()
    vim.api.nvim_feedkeys(vim.api.nvim_replace_termcodes("holo", true, false, true), "t", false)
end, opts)

which simply shrink one char at two side as a workaround for too aggressive in incremental selection
but this plugin will ignore this changed selection range and after I type bs and type CR again it will expand further like I don't type bs, which behaves different of treesitter' orignal one.
