Harpoon2: Wrong state is loaded when working with multiple tabs - having different working dirs

When opening a tab, and setting a different working folder in the new tab, the harpoon list is not loaded next time I start neovim.

I believe that the issue occurs because the data file uses the hash of the current working directory for to generate the file name.

local function fullpath(config)
    local h = hash(filename(config))
    return string.format("%s/%s.json", data_path, h)
end

When neovim loads, it uses the hash of the initial working folder, but when I open a new tab with a different working folder, it appears that the hash of the new working folder is used when saving the lists. So now lists are saved in a different file than the one loaded at startup.

Is there a reason for the hashing rather than one file?

The data file already contains data for multiple working directories already.
