`live-markdown` + `native-stack` + `fabric` causes incorrect layout when keyboard is open on Android

[kirillzyusko]

Description

If you use @expensify/react-native-live-markdown with native-stack (and new arch enabled) then input is obscured by the keyboard even if adjustResize is specified for softInputMode.

Actually I don't know if it's correct repo to open an issue or it should be opened in @expensify/react-native-live-markdown, because:

• native-stack + TextInput from RN -> everything is working fine
• stack + live-markdown -> everything works fine
• stack + TextInput from RN -> everything is working fine
• native-stack + live-markdown produces incorrect layout.

The reason why I open it here because if you inspect elements in layout inspector then you can notice, that next children to Screen has incorrect layout (and I tend to think that the problem comes from RNS, but feel free to correct me - if you think it's live-markdown issue, let me know and I'll re-open issue there):

Initially I opened issue in react-native-screens repository https://github.com/software-mansion/react-native-screens/issues/2124

@tomekzaw may I ask you to look into it? We're trying to integrate native-stack navigator in Expensify app and it's the only one blocker that remains 😔

At least would be good to understand if it's caused by live-markdown or conflict is somewhere else 👀

Hey @kirillzyusko, thanks for submitting this issue and preparing the minimal repro.

I confirm the problem is reproducible on my end.

We will investigate this issue.

edit: The problem goes away when I comment out registering MarkdownCommitHook, perhaps there's something wrong in there.

@kirillzyusko This should be fixing the problem: https://github.com/facebook/react-native/pull/44796, but I guess you will need to use a patch for now 😞.

[kirillzyusko]

@j-piasecki interesting 🤔 Originally I discovered this problem in Expensify app and then prepared a reproduction example.

But in Expensify it looks like we already include state during a copy:

    childNode = parentNode.clone({
        ShadowNodeFragment::propsPlaceholder(),
        std::make_shared<ShadowNode::ListOfShared>(children),
        parentNode.getState(),
    });

Interesting, I'll need to allocate some more time to test everything again more carefully 👍 I'll get back to you when I have tests results. Thank you for taking a look on this issue @j-piasecki and @tomekzaw ❤️

@kirillzyusko Did you manage to find the root cause of the issue?

[kirillzyusko]

@tomekzaw no, not yet. I'm waiting for RN 0.74 to land in Expensify and then will verify all fixes related to native-stack at once 👀

[tomekzaw]

@kirillzyusko E/App was upgraded React Native 0.75, could you please revisit this issue?

[kirillzyusko]

@tomekzaw I think @chrispader is going to check that, because he took over this task 👀

[tomekzaw]

Cool, thanks in advance!

[tomekzaw]

@chrispader Just a friendly ping, did you manage to take over this task?

[kirillzyusko]

@tomekzaw I am currently working on this task and the issue is not reproducible anymore. I think we can close this issue :)
