Character duplication when attempting to insert diacritic on macOS

[kevinushey]

On macOS, it's possible to insert diacritics on the press and hold of a keyboard button when the ApplePressAndHoldEnabled option is on (which I believe it is by default). For example, one could insert į by holding down the I key, and then pressing 5.

When performing this action in the Ace Kitchen Sink + Safari 11.0.2, I see that an initial i is inserted (which appears to be the expected behavior in all applications), but the newly inserted į following does not remove the original i. See e.g.

In case you want to try testing yourself but see the character repeated instead of a diacritic menu being shown, you can run

defaults write -g ApplePressAndHoldEnabled -bool true

in the terminal, and then restart Safari and re-navigate to the Ace kitchen sink.

This should be fixed by #3635, please let us know if you still can reproduce this on http://ace.c9.io. Thanks.

I can confirm that this appears to be fixed. Thanks!
