Thank you for your contribution @bleroux!
@dkwingsmt is this an acceptable approach to handling the hardware_keyboard physical/logical key mismatch error on web? From my understanding, the code here is written to map logical keys on web similar to how other platforms do it - however, I think only the browser emits extra "Process" key events for special characters like IME composition, emojis, etc

Yeah I think so. Actually I wonder why I didn't do it in the first place. Since the up event should always have the same logical key as the down event, this looks very idiomatic.

Thank you for the fix! This is definitely an edge case I didn't think about before. |

Description
On Web, browsers can emit key events with a logical key sets to
Processduring composition.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.
