Breakpoints do not work when running tests

Describe the bug

Hello,

I'm having trouble getting breakpoints to work when running tests.

They work fine when running a main class.

However when running a test, the debugger stop, but nothing shows up in the dap ui (frames, scopes etc.). When I resume the session the test runner resumes normally.

Everything works fine in VSCode:

In another repository I get a "breakpointRejected" message, but I couldn't find any information about where that can come from.

Expected behavior

the debugger should stop at breakpoints normally when running tests.

Thanks for the report @kimlai. I'll need to dig in and look at the DAP communication for this to see what's going on. I'll report back when I have some time to look at it.
