For example, the behavior is confirmed with Firefox 44.0.2 and Google Chrome xx.xx.xx and could not be reproduced in Firefox but Chrome or what ever.

Because of #89, I'm not going to investigate this sorry but I'll keep it open for others.

Here is a quick & dirty solution for chrome:

1. install stylish plugin
2. create a custom style to overwrite the default style

.cm-fat-cursor .CodeMirror-cursor {
    width: 7px;   /* default auto */
}

then the cursor in vim mode covers only one letter width
but chinese character not woking :(
