[v0.6.3] errors on animations with windows d2.exe -w

[Melandel]

Hi, love the work!

In version 0.6.3, I also get a lot of activity (mainly retries, to be accurate), with accompanying errors.

Reproduction

Given the following sandbox.d2:

# Root board

x -> y

layers: {
  # Board named "numbers" that does not inherit anything from root

  numbers: {
    1 -> 2
  }
}

When I do the following actions:

• d2.exe -w sandbox.d2
• save sandbox.d2 without any changes beforehand

Then I get the following logs:

Analysis

It seems that for some reason d2 tries to watch the bundle folder & files - triggering the following:

• for the sandbox/ folder: err: failed to watch "sandbox": GetFileAttributes: The system cannot find the path specified. (retrying in 2s)
• for the sandbox/index.svg file: err: failed to watch "sandbox\\index.svg": GetFileAttributes: The system cannot find the path specified. (retrying in 2s) after a receiving a REMOVE event
