Prerequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v8.x

Current Behavior

Page 1 has split pane. Page 2 has regular menu. Both pages share the same menu component. When navigating from Page 1 to Page 2, the collapsible Menu is not visible and the IonMenuButton is not visible. Forcing it visible does not make the Menu work. When going back to Page 1, the Split Pane is NOT visible. Refreshing on Page 1 makes the Split Pane layout appear again.

Expected Behavior

When navigating back to Page 1 from Page 2, the Split Pane layout should be visible as if the full pages are completely re-rendered.

Steps to Reproduce

Make a basic React Ionic SPA with IonRouterOutlet. Example is in the stackblitz. Observer Page 1 has Split Pane, Navigate to Page 2, go back to Page 1. Observe Split Pane is missing. Refresh page. Observe Split Pane is visible again.

Additional Information

I'm trying to update an app to show the Menu component on all pages (so the Split Pane Layout) except for one page which I want to have the Menu toggleable like on mobile UI because I have another Menu-like component which I want to show on the same side. I tried to make the Split Pane layout global for the app and just switch between apps but had a hard time hiding the split pane on the page I want it hidden, so I reverted to having the Menu (and Split Pane) on each page of my app, but now I'm getting this issue with the Pane not behaving as expected.

@TermoZour , it seems split pane on going back to page 1 is visible on the following link->[https://stackblitz.com/edit/ionic-splitpane-layout-menu-combo?file=src%2Fpages%2FPage1.tsx]

Are you facing this issue ?

[TermoZour]

It seems that now when I navigate back in stackblitz, there is a full page refresh. Like mentioned in the issue, a full page refresh fixes the Split Pane.

I have replicated the same code on a repo locally, and it seems that when navigating from page 2 to page 1, the Split Pane appears coorectly on page 1, but when navigating to page 2, I can't open the Menu unless I full refresh the website while being on page 2. I have attached a video of the issue as it appears on my screen.
