[webview_flutter] The click event is not pressed on iOS 18.2.

[ttb-inc]

Steps to reproduce

See the sample code.

1. Try pressing the button in the webview (checks OK)
2. Try pressing the FloatingActionButton '+' (UI event)
3. Try pressing the button in the webview again (to check for errors).
4. After pressing the 'Reload' button, reload the webview.
5. Try pressing the button in the webview (checks OK)

Expected results

Actual results

After the event of the flutter Button UI is pressed, the event of the webview is not pressed.

The error occurs only on iOS 18.2.
Works fine on iOS 18.1.1 and earlier.

If I'm doing something wrong or need additional options, please help.
Thanks a lot.

I'm using several flutter UIs on webview.
I'm experiencing a lot of issues.
I don't know if this is an iOS 18.2 issue, flutter SDK issue, or webview_flutter package issue.
Thank you.

@ttb-inc this was corrected in 3.27.1. Be aware of graphic issues with Impeller, though.
