`runner.isolated_filesystem()` assumes that the current directory in has not been deleted. But the various temporary directory utilities in `pytest` work by creating directories and then deleting them.
Maybe there's a larger problem here that I play a bit fast and loose with `os.chdir()` in both the test suite and in various lines of code in Datasette itself (in particular in the publish commands)?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",956303470,Tests failing with FileNotFoundError in runner.isolated_filesystem,
