Export variable of array type will ignore its own type and use the value's type when pasting value

[Rindbee]

Godot version

v4.0.stable.official [92bee43], v4.1.beta.custom_build [19e7490]

System information

Linux Mint 21.1 (Vera) - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1050 Ti (nvidia; 515.105.01) - Intel(R) Core(TM) i5-7300HQ CPU @ 2.50GHz (4 Threads)

Issue description

Peek.2023-06-24.07-21.mp4

Export variable of array type will ignore its own type and use the value's type when pasting a value of a different type.

ERROR: Invalid method 'size' for type 'int'.
   at: _variant_call_error (core/variant/variant.cpp:3625)
ERROR: Invalid method 'resize' for type 'int'.
   at: _variant_call_error (core/variant/variant.cpp:3625)

Steps to reproduce

1. Export an array;
2. Copy a value from another property of a different type;
3. Paste into that exported variable;
4. An error message will be output, but it still looks like an Array in the Inspector.

Minimal reproduction project

N/A

[ajreckof]

this was fixed by #80977

[Rindbee]

Doesn't seem to be fixed.
Pasting values of non-matching types causes non-empty arrays to appear as "(Nil)Array".

The editor will crash while clicking the Add Element button or the revert icon.

[ajreckof]

the nil part is intended it is reverted to null because the value is considered absurd. the crash on the other hand is a totally different bug which is introduced by #80706.
