It turned out that an issue https://issues.redhat.com/browse/CRW-1543 is reopened after documentation is pushed to production pre-release testing of CRW 2.7.0.

So, it's needed to move "Debug stops at the breakpoint only if breakpoint set up during debug session in a Quarkus workspace" issue from CRW 2.7 "Release Notes" [1] to CRW 2.7 "Known Issues" [2] on public documentation site.
