Cursor stuck to the top line when using <C-d>

[BartSte]

Problem

When placing the cursur on the top line, and then pressing , will not center the cursor. Instead it will stay stuck at the top. You can reproduce this by:

Reproduce

• Checkout branch main @ e1a63cc (latest commit when writing this)
• Ensure vim.o.scrolloff is 0.
• Config

return {
    'arnamak/stay-centered.nvim',
    config = function()
        require('stay-centered').setup( { allow_scroll_move = true })
    end,
}

• Do the following: gg<C-d>

Cause

For some reason, the if statement of plugin.lua:34 is entered as the line and top are equal. I am not sure, but I think the top variable is wrong. As a result the funtion exits early, missing the norm! zz command.

Workaround

As a workaround you can set allow_scroll_move = false.
