Do not reset scroll on atlas region editor

[hydroper]

Describe the project you are working on

RPG

Describe the problem or limitation you are having in your project

Everytime I re-open the atlas region editor, the scroll resets if I click anywhere for the first time in the image to select a region; however the scroll starts in the expected position (that is, when I open the region selector, the Godot editor scrolls to the last position I've been dragging around).

To clarify, I'm opening the atlas region selector multiple times, and the last time I open it, it scrolls to the correct position (the one from the previous selected region, including zoom). However, if I click for the first time after opening the region selector again, it resets the scroll (the verticall scroll, I guess).

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Since the scroll is retained from the last time you selected a region from an image, do not, after a click somewhere, reset its initial scroll positions.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Just a fix. This can be almost considered a bug.

If this enhancement will not be used often, can it be worked around with a few lines of script?

N/A

Is there a reason why this should be core and not an add-on in the asset library?

If I remember correctly, it's a bug that fixed in 4.1.
godotengine/godot#78091
Or maybe I misunderstood description.

@arkology I'm using Godot 4.1rc2 as of the writing. It's not related to preview too (related to the region selector).
