[pgadmin-hackers] Problems editing Queries with pgAdmin4

How can I report an issue for pgadmin4? I've had a lot of problems editing queries in the last version (4), today I upgraded to the last release and the problem is there yet.

When one is modifying any query even a new one, the editor freezes some text zones, and 

is impossible edit it, I don't understand why it happens, seems a html editor bug.

Thanks.
