Strange spurious key presses when using key::toggle

[Pauan]

Run the following code (warning it causes an infinite loop):

use std::thread::sleep;
use std::time::Duration;
use autopilot::key::Character;

loop {
    autopilot::key::toggle(&Character('s'), true, &[], 0);
    sleep(Duration::from_millis(100));
    autopilot::key::toggle(&Character('s'), false, &[], 0);

    sleep(Duration::from_millis(100));
}

This code will infinitely press the s key. While it is pressing the s key, repeatedly tap the y key on your keyboard.

You will see a pattern like this:

sssssssy;y;y;syy;y;y;y;y;yssy;y;y;sysy;y;y;y;y;yy;y;y;y;y;y;sssssssssssssysy;y;y;yy;y;y;y;yy;y;;sss

Even though the code is not pressing the ; key, and you did not press the ; key, it still causes spurious ; presses.

I don't know if this is a bug with autopilot, XTest, or perhaps my specific hardware. It's a very strange bug.

I also tested tfc, it has exactly the same problem with unicode_char_down, however ascii_char_down works perfectly fine. So it seems to be a bug in the conversion between Unicode -> key.
