Incorrect Connection Top Bound For Blocks Dragged From Palette

Expected Behavior

The bounds in which blocks will connect to others from all sides should be consistent regardless of if it was already in the editor or was currently being dragged from the palette for the first time

Actual Behavior

The top of this bound becomes extremely small when first dragging a block from the palette -- so much so that dragged block needs to become so low that it's overlapping for the connection to be recognized!

Steps to Reproduce

1. Place any stackable, non-hat block in the editor
2. Grab a block non-terminating stackable block for the palette (for example a hat block) and attempt to connect it above the previously placed block

System Details

Reproduced with consistent results on:
Chromium 144.0.7559.109 on Debian Bookworm
Safari 18.7.5 on iOS 18.7.7

Start by reproducing the connection-boundary difference in the block editor using the listed steps, comparing a block dragged from the palette with one already placed. Trace how the top connection bound is calculated during the initial drag, then verify that palette-dragged blocks accept connections from the same distance as placed blocks in Chromium and Safari.
