Additional Information

I have searched for existing issues,such as #24475,
It's good on Android 12(Android System WebView 96.0.4664.61),
but it doesn't work on Android 9（Android System WebView 69.0.3497.100）.

Thanks for the issue. Are you able to update the system webview on the Android 9 device? Version 69 is quite old and likely to have some issues that have been resolved in newer versions.

[zhuhuanzi]

@liamdebeasi Thank you for your answer. but in china the network environment is not open,we can't use Google's features. update webView is very difficult.

[zhuhuanzi]

@liamdebeasi update webview is not feasible,more than one software may appear in the system,the system is still running at a lower version.

[liamdebeasi]

Thanks for the update. Let me check with the team on this. The issue is likely a bug in an older version of the Chrome/Android WebView. Unfortunately, I do not have access to that version of the webview, making it hard to develop a workaround at the moment.

My colleague was able to reproduce this on an older Android 9 simulator. I will assign the bug label.
