Currently when a text field is focused, the framework sends a relatively large amount of data (especially on iOS) to the platform text input plugin. This is probably not currently measured / monitored by any benchmark as the data transmission is usually only triggered on text layout changes or when the text field scrolls.

Since a text entering/deleting benchmark will have to include the time spent interacting with the OS text input system it could be very flaky but it will still be great if we can get a warning when a change renders text input unusable.
