LineEdit with suggestions

Godot Version

Godot 4.3+

Hello,
thanks to @mrcdk in this thread How to dynamically show search results of LineEdit - #5 by mrcdk

I got the line edit with suggestions as you type working in Godot 4.2.2
It needs the embedded subwindows option ticked in the project settings, as mentioned in the post.

It works great in Godot 4.2.2, but starting with Godot 4.3+ the popup menu always steals the focus when it shows up.

I’m once again asking for your wisdom!
