R: Test explorer does not register tests run a in a loop

testthat tests written in a loop do not appear to be captured by the test explorer. I'm not sure if this is the same issues as #7213.

I have a testing file that loops through running several variations of the same set of tests (here: https://github.com/redoc-dev/redoc/blob/roundtrip-testing/tests/testthat/test-roundtrip.R#L12-L35). They run fine in the console, terminal, or the RStudio testing pane. When running via Positron test explorer, none of these tests are picked up. It does appear to be running them, as it takes a similar amount of time. But in "Test Results" I get the message * The test run did not record any output., and while the test file shows in the testing pane, no tests appear below it:

Were there any error messages in the UI, Output panel, or Developer Tools console?

I think not

Reproduce the issue with the linked tests/testthat/test-roundtrip.R example, especially lines 12-35, and observe the Positron test explorer and Test Results output. Trace how the looped tests are discovered or recorded; done means the individual tests appear under the file and their results are recorded.
