Chrome crash: Attempt to invoke virtual method "long android.view.accessibility.AccessibilityNodeInfo.getSourceNodeId()" on a null object reference

Question

While working on the Search form (JavaScript, CSS, HTML) of my web page, the Chrome browser (Android 10) crashes every time when I click on the web search icon and the input field is focused.

The debug stack trace in the crash report says

Attempt to invoke virtual method "long android.view.accessibility.AccessibilityNodeInfo.getSourceNodeId()" on a null object reference
at android.view.View.populateVirtualStructure(View.java:9942)

This crash obviously is a bug. The question is: where should I create the bug ticket?

I found the description of the AccessibilityNodeInfo, it seems to be a basic Android feature: https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo

I also found in this discussion https://meta.stackexchange.com/questions/369434/trying-to-comment-on-a-particular-question-on-the-full-site-crashes-android-chro that the Android Accessibility Service or the AutoFill Service might be involved in this.

Indeed, when I turn off the AutoFill feature of my KeePass password manager, Chrome no longer crashes.

So:

1. a form field on my web page is focused.
2. Then, chrome gives the focus event to the autofill Service
3. The AutoFill Service checks if there are some search suggestions or other insertable texts
4. The KeePass AutoFill feature is called.

As I am no Java/Android App developer, I need your help to find the correct recipient for this issue:

1. Could my HTML/CSS/JS code be responsible for this problem? (The search field only crashes on one special page and works fine on others)

2. Is this a chrome@android bug?

3. Is this a bug in the Accessibility Service of Android?

4. Or could it be a bug in the KeePass App for Android?

Which steps would you recommend to identify the clear source of the bug?

Thank you!
