Ctrl-Z on Windows causes unexpcted autocomplete triggering

[mikeful]

I'm testing this in Chrome on Windows 7.

After typing "This is a test." hitting Ctrl-Z few times causes autocomplete to trigger on each undo event resulting eventually text to transform into "Theengntosuendhermt".

I was expecting autocompletes to be ingored on undos.
