@dfalbel This PR has a few test failures that look like they might be related to the changes -- could you retry the tests if the failures look spurious, or investigate?

    Error: Timed out 90000ms waiting for expect(locator).toHaveText(expected)

    Locator: locator('.console-instance[style*="z-index: auto"] .active-line-number')
    Expected string: ">>>"
    Received: <element(s) not found>
    Call log:
      - expect.toHaveText with timeout 90000ms
      - waiting for locator('.console-instance[style*="z-index: auto"] .active-line-number')
