Cannot close popover by clicking backdrop after upgrading to 9.0

[mayswind]

• Framework7 version: 9.0.1
• Platform and Target: iOS 26.1
• Live Link or CodeSandbox: https://codesandbox.io/p/devbox/54cd4y or the code in sandbox.zip

Describe the bug

After upgrading to Framework7 9.0, I found that the popover seems to trigger popoverOpened twice because of the following code. This causes the click handler to be registered twice.

After switching to other pages, any click attempts to interact with a destroyed popover, which then leads to errors, and popovers on subsequent pages can no longer be closed by tapping the backdrop.

To Reproduce

Steps to reproduce the behavior:

1. Open the above CodeSandbox link
2. Click '1, First Show Popover'
3. Click '2, Then Go to Page2'
4. Click '3, Then Go to Page3'
5. Click '4, Then Show Popover'
6. Then, you will see the below error in the console, and you cannot close the popover by clicking the backdrop

Expected behavior

Can close popover by clicking backdrop.
