System Information
Operating system: Linux-6.5.0-26-generic-x86_64-with-glibc2.38 64 Bits, X11 UI
Graphics card: NVIDIA GeForce RTX 3060 Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 545.29.06

Blender Version
Broken: version: 4.2.0 Alpha, branch: main (modified), commit date: 2024-03-24 07:52, hash: af0c42e266a4
Worked: (newest version of Blender that worked as expected)

Short description of error
An import operator’s invocation can be defined so it shows a properties dialog if called from a file handler, or a file selector otherwise. For this to work, common properties such as files, directory and filepath should be 'HIDDEN' so they don’t show up in either interface.

These properties are effectively hidden on first invocation, but if the file selector is shown once, they are shown on later invocations through drag and drop.

Exact steps for others to reproduce the error

Execute this script to register a simple import operator and file handler: test_import.py
Drag and drop a .txt file into Blender. This popup appears:
Call the operator manually by hitting F3 and typing “Test Import”. The file selector appears.
Cancel.
Drag and drop a .txt file into Blender. Now this popup appears, with properties that should be hidden:

Its a space file bug, when the operator invokes the file select window, the draw call set HIDDEN this props, and later it removes the HIDDEN flag

Can confirm. This does not happen with Cpp IO operators. Guess I need to check this in debug build
