Editor stuck in re-import loop when it can't import textures

[passivestar]

Tested versions

v4.3.dev.custom_build [4a01602]

System information

Godot v4.3.dev (4a01602) - macOS 14.4.0 - Vulkan (Forward+) - integrated Apple M1 Max - Apple M1 Max (10 Threads)

Issue description

More aftermath of #76991. Stops when the "Import Resources When Unfocused" is disabled

Screen.Recording.mp4

P.S I'm also wondering why those textures fail to load in the first place, they are perfectly fine jpegs

Opened an issue for that: #91600

It's not specific to textures: the same thing also happens if Godot fails to import Blender files (#80049, #82888) and FBX files (#85402). And I don't think it's a new problem either.

As far as I can tell, this happens because the editor re-tries the import as soon as the progress dialog closes and the main editor window gains focus again.
