0.9.0 on Blender 4.2.3 Problem with Isolated channel

[kunigavlad]

Hi, I am using the latest version of blender_vertex_color_master 0.9.0alpha on Blender 4.2.3.

In a previous version (0.8.6), there was an issue with isolated channels #50, which was fixed in the 0.9.0 version.

However, a new problem has appeared. When using a second UV channel, the isolated channel displays as full white.

Steps to reproduce:

Add a cube.
Paint some vertex colors.
Add a new UV map.
You will see the isolated channel turn white.

Removing the second UV map restores the isolation display.
