Random selection of contributtions used to load file

[Czaki]

• npe2 version: 0.7.0
• Python version: 3.9
• Operating System: Ubuntu 22.04

The PartSeg provides two contributions:

1. PartSeg.load_image - load tiff image

2. PartSeg.load_masked_image -load tiff image and mask (as labels layer) from file {image_path_without_suffix}_mask.tif. It looks like napari selects by random which contribution use to load this image. You could see the film below when multiple open operations ends with a different result for loading (without recording it flickers faster).

napari_open-2023-06-16_10.27.27.mp4

This happens on napari from the repository, and the latest released PartSeg.

Example files that could be used to reproduce:

stack1_component1.zip

@Czaki thanks for raising. If this is at the level of a single plugin with multiple contributions, I think it's quite possible we've got undefined/undesired behaviours in there. From the napari API we don't pass through any information below the plugin level afaik, so I think you're right it'll be in the read logic here. Will look into it 🙏
