Sorry for the delay. I will open a new ticket about inconsistencies in
braces behavior and how it results in issue with paren blinking. I
understand that there is no clear solution for this problem at the
moment and will appreciate any improvements. We will try to restructure
our grammar to not threat "{" as neither token in grammars and will see
how it goes. Thanks a lot for the answers!
