pgAdmin4 Web - Query Tool Frozen/Blank

**Problem:** I've installed the latest web version of pgAdmin4: 9.6, using the official pgAdmin Docker image: dpage/pgadmin4, and all seems to be working fine, except the main tool: "query tool", when I click on "query tool" icon, it just keeps opening blank tabs. (can't even close them) **Tried:** - logging off - restarting image - resetting layout - reinstalling 9.6 - trying with 9.5 - trying with 9.1 **Notes:** - I've tested the DB and connection string of the same DB on my Desktop version of pgAdmin(also 9.6) and everything works, including "query tool" (so the DB and connection string are fine...have only issues with this docker web versions)
