## Description On Web, browsers can emit key events with a logical key sets to `Process` during compostion. It is usually not a problem, but in some edge cases (for instance when the browser window lost focus and some keys events were missed), the Flutter web engine might synthesize an up event with a logical key value different that the one used for the down event and this will lead to an assertion message on the framework side. ## Related Issue Fixes https://github.com/flutter/flutter/issues/126247. ## Tests Adds 1 test.
