bug: URGENT- Blocks software update - Menu disappear when navigate between multiple menus

Bug Report

Ionic version:

[x] 4.8

It blocks my next ionic update for my mobile app. I need a fast Bug Fix on this.

Current behavior:

I have a left side menu(menu 1). When I click on one of the buttons in the menu, it brings me to another page with a different menu (menu 2). I can navigate in this menu (menu 2)(what it suppose to do.) In this menu, I’m having a ‘back’ button to return to the last page (which contains menu 1). When I click on this button, we back to the page of the menu 1, but the menu disappear and we can’t open it in any ways. When I refresh the page, the menu 1 is back and everything is Ok.

Expected behavior:

When I click on menu 2 ‘back’ button to return to menu 1, it returns and shows the first menu correctly, then we can click on ‘go to menu 2’ etc.

I’ve tried v4.9 and nothing has changed. I tried @iamkinetic repo, the navigation is different but the bug is the same.
