Images that support transparency are not sliced accurately when slicing Type is set to Automatic in Sprite Editor

Package: 2D Sprite


How to reproduce:
1. Open user's attached '' project
2. Select Assets -> Textures -> spritesheet
3. Open Sprite Editor in the Inspector
4. Select Slice dropdown and click Slice button

Expected result: "+" and "-" signs are sliced into separate sprites
Actual result: "+" and "-" signs are sliced into one sprite

Reproducible with: 2017.4.35f1, 2018.4.13f1, 2019.2.14f1 (1.0.0), 2019.3.0f1 (1.0.0), 2020.1.0a14 (1.0.0)

- 2017.4, 2018.4 Sprite Editor is not included in the package
- Reproducible with PNG, PSD image formats

  1. Resolution Note:

    The Sprite Editor attempts to automatically slice and locate Sprites with a minimum threshold size of at least 4 pixels. This is to ensure that small artifacts in the texture (less than 4 pixels in size) will not result in unwarranted Sprites being created.

    For this issue, the minus sign Sprite is less than the minimum threshold required for automated slicing. This causes it to be grouped up with the prior plus sign Sprite. To adjust this, please manually create the Sprites for both the plus and minus sign in the Sprite Editor after slicing the other Sprites.
