Cannot use quotes on SQL Editor in 6.3.9 GA (no replies)

After upgrade to Workbench 6.3.9 GA, quotes are unavailable on SQL Query Editor. When i digit any quotes (simple ', double " or escape `) the editor returns none information.

To digit any quotes i'm use other text editor, then copy and paste to Mysql Workbench.

I'm using a macOS Sierra 10.12.3 and MySQL Workbench 6.3.9 10690321 CE 64 bits.
