Garbage characters appear at the text area when inputting CJK characters.

Steps:

1. Go to Node-red flow editor and add a function, template or comment node
2. Double click it to edit.
3. Move the cursor to the text area（Function, template or Body)
4. Switch the IME to Japanese and input some Japanese characters.
   And then, you can see some garbage characters at the beginning of the line.

I suspect this is due to the underlying Ace editor - see this open issue
ajaxorg/ace#2855

Should be related to ajaxorg/ace#1401, looks like they landed in master.

Tested in the live demo directly at https://ace.c9.io, they no longer have this issue.

Thanks for the heads up - not quite made it to the builds yet.

We upgraded ACE a few releases ago - so this issue should be resolved now.
