Thanks for the detailed question!

This doesn't look like an issue with 'mini.sessions', but rather a code snippet from 'nui.nvim'. The reason is that input items to vim.ui.select() are plain strings. The 'nui.nvim' code has the line of local format_item = opts.format_item or function(item) return tostring(item.__raw_item or item) end (meaning format_item is equal to opts.format_item if it is supplied) which later is used with the transformed item (after if type(item) ~= 'table' then item = { __raw_item = item } end) and not with the original item. This is not according to the specification, see :h vim.ui.select().
