Pressing "return", "escape", etc. keys in input causes trigger of "input" event listener in <=IE9 and Opera Classic. In those browsers "input" event is not implemented or it is implemented improperly. Angular fixes it by listening to "keydown" event. Line:

if (key === 91 || (15 < key && key < 19) || (37 <= key && key <= 40)) return;

shows, that few keys, that does not change input value, are filtered out in handler. Keys "return", "escape", etc., which do not change value of input, are not filtered out, which causes a lot of problems.
