### Screenshots

### What browsers are you seeing the problem in?

_No response_

### How can we reproduce this issue?

Here's a fork of the bug:
Components in this fork are on v1.5.0
https://stackblitz.com/edit/vitejs-vite-iysux6uy?file=src%2Fmy-element.ts,package.json,index.html

Open the console, and toggle the device toolbar. Pick iPad as the device.
Click the menu, select an item. Asset in the console that "changed!" is logged twice.
Components v1.4.0 or earlier do not show the double invocation of the `@change` callback.

Issue is reproducible using the device emulator in Chrome as well as using the iPad emulator on Mac.
I can be reached internally @connorr on slack.

### Would you like to track this issue in Jira?

- [x] Yes, please tell me the ticket number!

Start with the linked StackBlitz reproduction and the ActionMenu component, comparing behavior between versions 1.4.0 and 1.5.0 on the iPad device emulator. Confirm that selecting an item invokes the @change callback twice, then verify that the callback is invoked once per action after the change.
