`expect_snapshot()` doesn't capture some output anymore (>= 3.3.2)

[etiennebacher]

expect_snapshot() doesn't capture some output anymore as of 3.3.2 and I don't see this documented in the changelog. I have this example:

tests/testthat/test-foo.R (this is the only test file)

test_that("my test", {
  expect_snapshot(tinytable::tt(mtcars[1, 1:2]))
})

With 3.3.1, it produces this snapshot:

# my test

    Code
      tinytable::tt(mtcars[1, 1:2])
    Output
      
      +-----+-----+
      | mpg | cyl |
      +=====+=====+
      | 21  | 6   |
      +-----+-----+ 

With 3.3.2, it produces this snapshot:

# my test

    Code
      tinytable::tt(mtcars[1, 1:2])

This change is surprising, is this expected? If so, it is worth mentioning in the changelog IMO.

Obviously it's not expected.

If I run tinytable::tt(mtcars[1, 1:2]) interactively it opens in the viewer, so the place to start would be to figure out why it used to behave differently in a snapshot and what has changed in the meantime.
