@FailingTest() annotation on test_reflective_loader test timeouts but fails faster without it #5761
Description
Describe the bug
Adding @FailingTest() to a failing test_reflective_loader test makes us hit a timeout (which could go away if we land #5620).
To Reproduce
Steps to reproduce the behavior:
- Clone https://dart-review.googlesource.com/c/sdk/+/456020 patchset 1
- Run the tests at
pkg/analysis_server/test/lsp/document_highlights_test.dart - See it gets stuck and times out (be sure you get a timeout, note the above issue I mentioned)
Expected behavior
For it to pass normally without a timeout as a success since it does fail.
