Summary Shift-Esc, or CapsLock-Esc, dispatches excessive keydown events

1) Navigate to about:blank 2) Open the console 3) run: window.addEventListener("keydown", function(e) { console.log(e)}) 4) Compare the number of events fired when using Esc on its own versus Shift-Esc or Esc while CapsLock is on On one of my sites, I get double Esc events when doing Shift/Caps-Esc. On about:blank, I get hundreds of extra events per frame. Firefox and Chrome don't exhibit this behaviour — they generate one event per key press (ignoring, of course, key repeat). Also had a friend repro this on a different machine, same issue. Affects current release of Safari (12.0.1, 14606.104.1.1) and Safari TP (r70, 12.1, 14607.1.13). Couldn't get WK nightly to launch, so I can't check there. Thanks for all your hard word, WebKit team!
