[WebGL] Input.GetKey gets stuck when changing focus



Steps to reproduce:
1. Download and open attached project ""
2. Build for WebGL including "Scene" scene
3. In browser, open up console
4. Press and hold left shift, while doing so, switch focus to other window
5. Go back to the browser window with built project

Actual result: Console keeps logging that the left shift is still being pressed
Expected result: Key does not stay pressed if focus is lost

    HI Team,

    I can still reproduce the issue.
    1. Press and hold key (monitor the input using Input.GetKey())
    2. While pressing and holding right click outside of the Unity Canvas
    3. Unity still receives Input.GetKey() as true even if no key is actually pressed

    Unity 3D used : 2017.2.1p2
    Browser : Chrome, Firefox

    This issue isn't fixed. Still present in 5.5.1f1

    1) Hold CTRL
    2) Click outside webGL canvas
    3) Release Control
    4) Return mouse cursor over canvas
    5) Even clicking back into the webGL canvas doesn't fix it, you have to press+release the key

    I can still reproduce a similar issue on 5.6.2f1 with these adjusted steps:
    3. In the WebGL build, hold down a key (in this example, Left Shift)
    4. Right-Click outside of the game view to bring up a context menu
    5. Release Left Shift
    6. Click on the game view
