sda) does not behave as explained in help

[cideM]

I am using the default configuration and I don't think that I have any plugins installed that would interfere with this. My plugins are:

        nvim-lspconfig
        vim-fugitive
        vim-rhubarb
        gitsigns-nvim
        vim-unimpaired
        vim-repeat
        vim-commentary
        vim-indent-object
        QFEnter
        nvim-treesitter-context
        fzf-lua
        vim-gutentags
        vim-dirvish
        leap-nvim
        vim-sandwich
        sad-vim
        copilot-vim
        vim-sayonara

        github-nvim-theme
        catppuccin-nvim

        vim-js
        vim-lua
        vim-jsx-pretty
        vim-nix
        vim-terraform

        nvim-treesitter.withAllGrammars

If my cursor is inside (foo) and I type sda) it aborts the sequence when I get to a and it tries to delete any pair of a's it finds. But according to :h sandwich:

    (foo)

press `sda(` deletes the parenthesis since the default textobject |a(| assigns
the region surrounded by "(" and ")" including them.
