 However, if you want a debugger I recommend using VSCode and the `playwright` extension, as the above command is a cruder debugger that steps into every function call which is annoying.
 With the extension you can set a breakpoint after `waitForDefaultPlanesVisibilityChange` in order to skip app loading, then the vscode debugger's "step over" is much better for being able to stay at the right level of abstraction as you debug the code.

 #### Some notes on CI
 
-The tests are broken into snapshot tests and non-snapshot tests, and they run in that order, they automatically commit new snap shots, so if you see an image commit check it was an intended change. If we have non-determinism in the snapshots such that they are always committing new images, hopefully this annoyance makes us fix them asap, if you notice this happening let Kurt know. But for the odd occasion  `git reset --hard HEAD~ && git push -f` is your friend.

 How to interpret failing playwright tests?
 If your tests fail, click through to the action and see that the tests failed on a line that includes `await page.getByTestId('loading').waitFor({ state: 'detached' })`, this means the test fail because the stream never started. It's you choice if you want to re-run the test, or ignore the failure.
