Exported PackedStringArray loses focus after each character is typed

[QueenOfSquiggles]

Godot version

4.1.beta3.mono [ada712e]

System information

Godot v4.1.beta3.mono - Manjaro Linux #1 SMP PREEMPT_DYNAMIC Sun Jun 4 12:31:46 UTC 2023 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1070 (nvidia; 530.41.03) - AMD Athlon(tm) X4 880K Quad Core Processor (4 Threads)

Issue description

For any script (GDScript and C# tested) that is exporting a PackedStringArray, the inspector behaves strangely. When adding an element in the editor, the LineEdit loses focus after each character is typed. So between typing each character I have to click on the element again.

For example, after typing the "a", the element lost focus and my further typing goes nowhere.

Steps to reproduce

Create a script that exports a PackedStringArray
Try to add an element with more than one character.

Minimal reproduction project

Can be recreated very quickly. Any script exporting a PackedStringArray (GDScript and C# tested).

Can confirm in v4.1.beta3.official [ada712e]
This is no longer reproducible in v4.1.beta.custom_build [afc5fa1].

My guess is, that it got fixed by #78643.
