The LayoutTest inspector/sources/debugger-breakpoints/dom-breakpoints.html runs perfectly in command-line whether or not PointerEvents are enabled (using --enable-blink-features=PointerEvent).

However, whenever the test is run for virtual/pointerevent test suite (which only takes the above command-line flag), the test fails. Here is a failures log, apparently no output was generated:

Any chance the test is not supposed to run for virtual test suites?

Here is the command-line I used to test locally successfully:
./out/Debug/content_shell \
  --enable-blink-features=PointerEvent \
  --run-layout-test \
