A revert of this CL has been created in
https://codereview.chromium.org/424213007/ by jchaffraix@chromium.org.

The reason for reverting is: The change broke several Chromium OS
interactive_ui_tests:

ExtensionPointerLockAccessFail
ExtensionPointerLockAccessPass
EscapingMouseLock
MouseLockSilentAfterTargetUnlock
TestTabDoesntExitMouseLockOnSubFrameNavigation
TestTabExitsMouseLockOnGoBack
TestTabExitsMouseLockOnNavigation
PointerLock_PointerLockLostWithFocus

that were using the prefixed API (""Uncaught TypeError: undefined is not a
function").

Linux and Mac were also impacted (I didn't triage them earlier sorry):
