Describe The Issue

I get type assignment warnings in my wezterm config whenever I do a custom key binding.
These are not exceptional extra custom key mappings, but mappings lifted directly from the wezterm docs.

This is an example minimal config pulled from https://wezterm.org/config/lua/keyassignment/AdjustPaneSize.html but added the @type Wezterm line at the top and wezterm.config_builder() to infer the type of config. This makes type checker errors appear.
Adding ---@type Config instead of using the wezterm.config_builder() also causes the same type issues.

---@type Wezterm
local wezterm = require("wezterm")
local act = wezterm.action
local config = wezterm.config_builder()

config.leader = { key = "a", mods = "CTRL" }
config.keys = {
	{
		key = "H",
		mods = "LEADER",
		action = act.AdjustPaneSize({ "Left", 5 }),
	},
	{
		key = "J",
		mods = "LEADER",
		action = act.AdjustPaneSize({ "Down", 5 }),
	},
	{ key = "K", mods = "LEADER", action = act.AdjustPaneSize({ "Up", 5 }) },
	{
		key = "L",
		mods = "LEADER",
		action = act.AdjustPaneSize({ "Right", 5 }),
	},
}
return config

Expected Types

I expect no type warnings to appear for such a common configuration use-case.

@reegnz Thanks for the feedback! Does 4280d03 fix this?

[reegnz]

@DrKJeff16 yupp, that seems to fix it! 🎉

[DrKJeff16]

Awesome! Let me know if there's anything else that could be improved.

[DrKJeff16]

@reegnz Forgot about you! I fixed this for good in #107. See #78 for more context.
