A crash occurred due to combining webviews with Android 12's new scroll overflow behavior. Applying `opacity: 0.99` prevents the crash from occurring. This change should be viewed as a temporary fix while we await a more appropriate solution for the `react-native-webview` library. react-native-webview/react-native-webview#1915 (comment)

Thanks for the quick fix @dcalhoun. I can confirm the changes resolved the error, tested on Pixel 6 and Galaxy S20. LGTM. 🚀
I did want to leave a note on how we might revisit the implementation and remove the workaround in the future. I'm fairly certain that using style and opacity fixes for functionality workarounds gives both of us pause, but after reviewing the react-native-webview thread, there doesn't seem like a better solution, either. I had also tried one of the other solutions in the thread, like androidLayerType="software", but that seems like just as much of a workaround.
This change should be viewed as a temporary fix while we await a more appropriate solution for the react-native-webview library.
Based on your work researching the thread, do you feel the ultimate solution is to wait for react-native-webview to release a fix? If so, how might we best "keep up" with the issue resolution from react-native-webview's end? This comment is more directed at the future of these files, and how we might manage adding workaround changes.

@derekblank definitely. I should have more explicitly conveyed this in my PR description.
Agreed. I explored this workaround as well, but feared possible performance issues from the change based upon comments on the thread and my own research. However, I do not fully understand the

Historically, my approach is subscribing to the relevant issues, and hoping that once it is resolved I remember what it is I need to do next after receiving a notification. Not the most sound approach. 🙃 One approach to tracking workarounds like this would be a single file implementing them. The benefits would be a single, documented location that clearly conveys the intentions for a workaround and how we remove them in the future.
@fluiddot thank you for sharing the additional findings. The age of the issue is disconcerting. 😞 I agree it is unlikely for us to see a proper solution from the library. It may require that we investigate a proper solution ourselves. |

What?
Fixes #42514. Apply a workaround to prevent a crash on Android when webviews are displayed within a scroll view. The crash appears to originate with incompatibility with Android 12's new overflow scroll behavior.
Why?
The editor crash creates a bad user experience with the possibility of content loss.
How?
Applying
opacity: 0.99prevents the crash from occurring. I perceive this change to be less than ideal, and should be considered a temporary fix while we seek a more appropriate solution for thereact-native-webviewlibrary.I explored other workarounds like
androidLayerType="software"as well, but feared possible performance issues from the change based upon react-native-webview/react-native-webview#1915 (comment) and my own research. However, I do not fully understand theopacity: 0.99workaround. It is possible that it similarly creates a "software layer."Testing Instructions
