Unexpected behavior during multiple cel selection + Cel Properties changes

[Gasparoken]

Issue 1:

• New Sprite
• Add a couple of frames.
• Draw something on frame 2
• Delete the cel on frame 1
• Double click on cel of frame 2 to open Cel Properties, don't close it.
• Select the cel range 1 to 3
• On Cel Properties modify the Color or Z-index or User data.
• Select the cel 2 (non-empty cel).
• Result: the properties were not modified. Expected: the modified fields would be modified in the non-empty cel.

Issue 2: unmodified fields are overwritten.

• New Sprite
• Add a couple of frames.
• Draw something on frame 1 and 2
• Double click on cel of frame 1 to open Cel Properties, don't close it.
• Add some user data for example "first frame"
• Select the cel range 1 to 3
• On Cel Properties modify just the Color.
• Select the cel 1 (non-empty cel).
• Result: user data was modified in all cels. Expected: Modify only cel colors. User data must be kept intact

Aseprite and System version

• Aseprite version: 1.3rc4
• System: macOS Ventura

I have a related problem where altering the Z-index with a bunch of cels in a selection also updates all of their color data, which is not my intention.
Does the linked fix also prevent this situation from happening?

That's right @shanianickel, it's related to this issue. We'll merge the fix for the next release.
