ETC1 + Alpha not working on UI Images when the used sprite is with 'Packing Tag' set

UI

-

Steps to reproduce:

1. Open the attached project
2. Make sure that:
Editor mode is set to Android
Texture 'bar_iso_energy' is set to Sprite, has a 'Packing Tag' set
and has 'Compress using ETC1 (split alpha channel)' enabled.
3. Play the scene
4. Notice the lower left image (UI Image) does not have alpha channel applied, while the one in the middle (Sprite renderer) does have.
5. Stop the scene
6. Delete the 'Packing Tag' of the 'bar_iso_energy' sprite
7. Play the scene again, notice both have alpha channel as expected

    I have always ETC2 output for sprites (for both: in atlases or not)

    It is crucial functionality for android 2D games and still not working in Unity 5.3.4p2 :/
    Please fix this issue.

    Yes, we must create several APK if we us Atlas packing with sprites variant. I must create a ETC2, a PVRTC, a ATC apk files.

    I prefer create one ETC1 + alpha and one ETC2.

    Please fix this issue for 2D game developer :)

    not having this is making android development incredibly difficult, especially for ui heavy games.
