Click and drag on any node in 3D incorrectly moves selected node

Godot v4.2.stable - Windows 10.0.19045 - Vulkan (Forward+) - dedicated AMD Radeon RX 6700 XT (Advanced Micro Devices, Inc.; 31.0.21023.2010) - AMD Ryzen 7 5800X 8-Core Processor (16 Threads)

Issue description

So this seems to be an old one, but got worse in 3.5 and 4.0, I couldn't find any other issues about this.

Basically when in Select Mode in the 3D editor, with a node selected, clicking and dragging on any node moves the currently selected node as if you had clicked on it, regardless of which node is under the mouse cursor. Prior to 3.5 this only happened with locked nodes under the mouse specifically.

I believe the correct behavior would be to move the node under the cursor, unless it is locked in which case a box selection would be started. This would be consistent with the 2D editor and would avoid the situation in the 3D editor where you cannot perform box selection because the background is obscured by locked nodes.

Current behavior:

• No node selected, click anything and drag -> box selection
• Node selected, click on any node and drag -> selected node moves
• Node selected, click on background and drag -> box selection

GIF demonstration, the sphere is locked:

Prior to 3.5 the behavior worked like this:

• No node selected, click background and drag -> box selection
• No node selected, click unlocked or locked node and drag -> node moves if unlocked, no box selection
• Node selected, click on any unlocked node and drag -> node under mouse is selected and moves
• Node selected, click on any locked node and drag -> selected node moves
• Node selected, click on background and drag -> box selection

GIF of 3.2 - 3.4 behavior (the sphere is locked)

It seems prior to 3.2 you could click and select locked nodes in the 3D editor and that seems to have prevented the bug from appearing at all.

Steps to reproduce

• Open the included Godot 4 project or create a blank project and add multiple objects into a 3d scene.
• Select one node
• (after 3.5) While staying in Select mode, click the mouse in the 3D view over a non-selected node and drag
• (prior to 3.5) click the mouse over a locked node and drag
