SDK: LrDevelopController.resetAllAdjustments() cancels modal dialog

Calling LrDevelopController.resetAllAdjustments() from within a modal dialog causes the dialog to exit with the return result of "cancel" (as if the user clicked the Cancel button).  This occurs with my LR 11.5 on Mac OS 12.4 but not on Windows 10.

To reproduce, put the following script in the Scripts folder, restart LR, and invoke the script from the Scripts menu.  Click the Reset button twice.

local LrApplicationView = import "LrApplicationView"
local LrDevelopController = import "LrDevelopController"
local LrDialogs = import "LrDialogs"
local LrTasks = import "LrTasks"
local LrView = import "LrView"

local f = LrView.osFactory()

LrTasks.startAsyncTask (function ()
    LrApplicationView.switchToModule ("develop")
    local result = LrDialogs.presentModalDialog {
        title = "Reset Develop Adjustments", 
        contents = f:push_button {title = "Reset",
            action = function ()
                LrDevelopController.resetAllDevelopAdjustments () 
                end}}
    LrDialogs.message ("LrDialog.presetModalDialog result", result)
    end)
