(fix/test): reset clearOnResize to true for size tests

- when false, canvas won't resize on window resize necessarily
  - was set false in previous test

- this was found when branch coverage was lacking a bit on resizing,
  now we're at ~93% and missing just one branch!
  - the tests didn't error out though because without input size the
    canvas size is 0 in these tests regardless of resize
    - not a perfect test in that sense :/ :/
