Clearing one of the values of TypedArray in the inspector makes the value unable to be found by the find function

[kus04e4ek]

Godot version

v4.1.2.rc1.official [58f0cae] and v4.2.dev5.official [e3e2528]

System information

Godot v4.1.2.rc1 - Windows 10.0.19044 - Vulkan (Compatibility) - NVIDIA GeForce GTX 1650 (NVIDIA; 31.0.15.3742) - AMD Ryzen 5 3550H with Radeon Vega Mobile Gfx (8 Threads)

Issue description

Clearing one of the values of a typed array in the inspector seems to just unreference value and not set it to <null>, so the value becomes <Object#null>. Array's find function seems to look for the <null> value and doesn't accept <Object#null>, even if in GDScript <Object#null> == <null>. So, when calling array.find(null) in the tool script, the function can't find anything. When the project is restarted or you run it, the values that were equal to <Object#null> will become <null>.

Steps to reproduce

1. Export a typed array of Resource or any of the types that inherit from it;
2. Set one of the values of a typed array to anything;
3. Clear the value;
4. Use array.find(null) in any of the tool scripts.
