[Bug]: Dialog demo doesn't focus first input on subsequent open by default

[romansp]

Environment

Reka UI v2.9.1

macOS Sequoia 15.7.4
Microsoft Edge 145.0.3800.97 (Official build) (arm64)
1Password for Edge extension 8.12.4.46

Safari 26.3 (20623.2.7.18.1)
1Password for Safari extension 8.12.5.2

Link to minimal reproduction

https://stackblitz.com/edit/y5qqkahm?file=src%2FApp.vue

Steps to reproduce

1. Go to minimal repro: https://stackblitz.com/edit/y5qqkahm?file=src%2FApp.vue
2. Open dialog first time. Name field is focused.
3. Close dialog.
4. Open dialog once again.

Describe the bug

Noticed that Dialog demo doesn't focus first input (Name) by default when you open dialog second time. Instead DialogContent container itself is focused.

I did some digging and it seems to be some strange interaction between Icon component from iconify and MutationObserver in FocusScope. The following is happening: Icon component sets CSS classes -> MutationObserver is triggered -> focus gets re-validated but moved to container instead. If you remove Icon component then focus behaves correctly.

Of course it's not just demo's issue and can be reproduced in apps.

UPDATE March 12
This seems to be caused by 1Password browser extension. Disabling this extensions restore correct focus behavior.

Expected behavior

First input (tabbable element) should be focused on dialog open every time.

Context & Screenshots (if applicable)

Thanks for reporting the issue @romansp . However I can't seems to reproduce the issue 🤔

@zernonia Sorry, I should've done more thorough investigation.

It turns out to be 1Password browser extension causing this and correct behavior is restored when I disable it. Here's my environment. I will update environment section in the original post as well.

Reproducible in:

1. macOS Sequoia 15.7.4
2. Microsoft Edge 145.0.3800.97 (Official build) (arm64)
3. 1Password for Edge extension 8.12.4.46

Also in Safari. In this case first tabbable input never receives initial focus. Not even on first open.

1. macOS Sequoia 15.7.4
2. Safari 26.3 (20623.2.7.18.1)
3. 1Password for Safari extension 8.12.5.2

I also recorded a video demonstrating what's happening:

I still find it very strange that removal of <Icon /> component also fixes this issue. Interestingly enough radix-ui Dialog demo isn't affected either.

I'm willing to spend some more time to try to figure out a clean workaround.
