### Bug Description

When inside a region you do not have access to, aiming at water, at just the right angle, so your client isn't selecting any block behind the water, as such: (https://i.imgur.com/uIA0HbX.png) as opposed to as such: (https://i.imgur.com/7MzAUji.png) you are able to bypass region protection, and place mob spawn eggs, spawning the mob.

### Expected Behavior

Respect region protection and do not allow item usage if not part of the region, regardless of how your client is aimed.

### Reproduction Steps

1. Create region.
2. Use a typical spawn egg, such as a cow spawn egg.
3. Aim at water as shown in first screenshot in Bug Description section.
4. Right click to place mob bypassing protection.

### Optional WorldGuard-Report

_No response_

### Anything Else?

Using block-entity-spawns-with-untraceable-cause: true - is a temporary solution, however this breaks a wide variety of other entity spawn related things on the server, to the point where running this setting on true is simply game-breaking.

Das Issue nennt keine Quelldateien oder Tests. Reproduziere den Bypass zunächst auf Paper 1.19.4 mit WorldGuard 7.0.8 und WorldEdit 7.2.15 und verfolge dann die Verarbeitung des Gebietsschutzes für spawn eggs, die auf Wasser zielen. Als erledigt gilt die Aufgabe, wenn das spawn egg bei seiner Verwendung in einem geschützten Gebiet unabhängig vom Zielwinkel blockiert wird, ohne auf den Workaround mit der fehlerhaften Konfiguration angewiesen zu sein.
