Infinite recursion with `vim.tbl_extend` / `vim.tbl_deep_extend`

It looks like if the code includes vim.tbl_extend or vim.tbl_deep_extend, the exported .json just keeps on writing to disk without end. `nvim -l reproduction.lua` Reproduction file: ```lua vim.opt.rtp:append(".") local profile = require("profile") profile.start("*") local options = {} for index=1,1 do vim.tbl_extend("force", options, { {foo={another=8}} }) -- vim.tbl_deep_extend("force", options, { {foo={another=8}} }) end profile.export("out.json") ``` Neovim version: ``` :version NVIM v0.11.0-dev-1075+gb34e137e43 Build type: RelWithDebInfo LuaJIT 2.1.1727870382 Run ":verbose version" for more info ```
