P: SDK: Can't call LrBinding.makePropertyTable() from scripts in Scripts folder

Calling LrBinding.makePropertyTable() in a script in the Lightroom Scripts folder always fails with the error:

"LrBinding.makePropertyTable: missing functionContext"

This prevents making simple scripts using LrDialogs. presentModalDialog(). It also makes it harder to file bug reports involving dialogs. 

To reproduce on LR 14.3 / Mac OS and / Windows 11, place this script in the Scripts folder:

local LrBinding = import "LrBinding"
local LrDialogs = import "LrDialogs"
local LrFunctionContext = import "LrFunctionContext"
local LrTasks = import "LrTasks"

LrFunctionContext.callWithContext ("X", function (context)
    local success, err = LrTasks.pcall (function ()
        LrBinding.makePropertyTable (context)
        end)
    LrDialogs.message (tostring (success), err)
    end)

LrFunctionContext.postAsyncTaskWithContext ("X", function (context)
    local success, err = LrTasks.pcall (function ()
        LrBinding.makePropertyTable (context)
        end)
    LrDialogs.message (tostring (success), err)
    end)

When you run it, it will fail with the errors:

But it runs correctly when run from a plugin or from my Debugging Toolkit's Debug Script command.
