Tilt includes the following change in their fork: main...tilt-dev:fsnotify:main

Windows allows filtering file events to include changes to file
attributes. However, when reporting the actual event, attribute
changes are included as FILE_ACTION_MODIFIED so it's impossible
to distinguish from file writes.

This means the library's op::Chmod is never actually populated
on Windows and so attribute changes aren't really usable. Since
the API does not support specifying an event type filter as a
caller, attribute changes on Windows are ignored rather than being
misreported.

and the README says:

• [Windows] File attribute changes are ignored
  • No Chmod operations will be detected or returned on Windows because the underlying Windows API does not support
    distinguishing these from Write operations
  • Some software (likely AV/security) can cause excessive attribute changes resulting in many spurious write events
    for otherwise unchanged files

Might want to consider including that here; it seems these events are never useful, and only cause problems. Need to look into it.
