Can't complete `:tag` with `tagfunc` set to `v:lua.vim.lsp.tagfunc`

[diktomat]

When using the LSP for tagfunc (see :h vim.lsp.tagfunc()), cmp complains that there's no tags file when using the :tag command. As this command is fully functioning without a tags file, this should not throw errors and instead complete just fine.

I have the same issue. That happens with ts (tree sitter) command too

Yes. It seems like no tagfunc works and the plugin goes straight for the tagfile. Does anyone know if it is possible to ignore a list of command or a regular expression to disable completion for it?

EDIT: Okay, this plugin is very slim and simply relies on the inbuilt :help getcompletion() function. 🤔
