withRegion + clearNode incorrectly clears not related sample targets

[velialiev]

What is the current behavior:

Removing region using clearNode removes not only relations with region units but with any other units that are used in the same sample target array as them

Please provide the steps to reproduce and if possible a minimal demo of the problem via https://share.effector.dev, https://codesandbox.io or similar

https://share.effector.dev/CfOXurO3

1. Create unit A in region R
2. Create unit B outside of a region R
3. Create sample outside of a region R with any clock C and target [A, B]
4. Clear region R
5. Trigger clock C
6. Both units A and B are not triggered

What is the expected behavior:

Expected unit B to be triggered since it and sample should not be cleared with region R

Which versions of effector packages, and which browser and OS are affected by this issue? Did this work in previous versions of effector?:

23.2.3

Issue looks very insidious and not easy to fix. In a meantime I suggest to use only one target per sample call when target is a unit from withRegion

This was one of the most challenging graph problems I've ever dealt with in my life 🫠
I had to significantly redo the logic, so if you find any more bugs, let me know
