-// NormalizingInputFilterMac is designed to solve the problem of missing keyup |
-// events on Mac. |
-// |
-// PROBLEM |
-// |
-// On Mac if user presses CMD and then C key there is no keyup event generated |
-// for C when user releases the C key before the CMD key. |
-// The cause is that CMD + C triggers a system action and Chrome injects only a |
-// keydown event for the C key. Safari shares the same behavior. |
-// |
-// SOLUTION |
-// |
-// When a keyup event for CMD key happens we will check all prior keydown |
-// events received and inject corresponding keyup events artificially, with |
-// the exception of: |
-// |
-// SHIFT, CONTROL, OPTION, LEFT CMD, RIGHT CMD and CAPS LOCK |
-// |
-// because they are reported by Chrome correctly. |
-// |
-// There are a couple cases that this solution doesn't work perfectly, one |
-// of them leads to duplicated keyup events. |
-// |
-// User performs this sequence of actions: |
-// |
-// CMD DOWN, C DOWN, CMD UP, C UP |
-// |
-// In this case the algorithm will generate: |
-// |
-// CMD DOWN, C DOWN, C UP, CMD UP, C UP |
-// |
-// Because we artificially generate keyup events the C UP event is duplicated |
-// as user releases the key after CMD key. This would not be a problem as the |
-// receiver end will drop this duplicated keyup event. |
