Platform: Chrome OS

Tests are encountering the following:

ERROR:KeyboardEventManager.cpp(440)] Not implemented reached in static bool blink::KeyboardEventManager::currentCapsLockState()

Code:
https://cs.chromium.org/chromium/src/third_party/WebKit/Source/core/input/KeyboardEventManager.cpp?q=KeyboardEventManager.cpp+package:%5Echromium$&l=440

Since this logs as an ERROR it looks suspicious in failing tests:

https://build.chromium.org/p/chromiumos.chromium/builders/amd64-generic-tot-chromium-pfq-informational/builds/11721

https://uberchromegw.corp.google.com/i/chromeos.chrome/builders/cyan-tot-chrome-pfq-informational/builds/1918

Although I suspect it may be a red herring.
