[Bug]: Playwright 1.43.0 UI mode clears results after tests finished executing

[ReactiveWarrior]

Version

1.43.0

Steps to reproduce

Steps to reproduce:

1. Clone my repo at https://github.com/ReactiveWarrior/playwright-ui-bug
2. npm install
3. npx playwright test --ui
4. Run all tests (F5)
5. See the tests finished executing
6. After ~1 sec. see the test results disappear (UI mode goes to IDLE state as if you just opened it)

Expected behavior

I expect to see the test results so that I could click on each test and see the logs, snapshots etc. Similarly what the trace viewer provides. I expect test results to preserve until I run the tests again or close the UI viewer.

Actual behavior

The bug is that after ~1 sec. since the tests finished executing, the test results disappear, the UI mode goes to IDLE state as if you just opened it.

Additional context

This bug happened right after I upgraded the Playwright version to 1.43.0.
