[Bug]? Resizing OHIF window causes viewport to scroll down to last slide reset Window Levels and colormap

[ahlaughland]

Describe the Bug

Not sure if this is a bug or a problem with the DICOM dataset I'm using - this doesn't happen on all datasets. When I resize the OHIF window the Axial view scrolls all the way to the bottom and resets the Window Levels and colormap.

I see a comment in the code for sliceIndex:
https://github.com/rapidllc/3drd-ohif-v3/commit/7624ccb5e495c0a151227a458d8d5bfb8babb22c#diff-a28c8c52c1ec95a73d2e55755c1baf5b8cfd47e511221277126c494c650ad1e5R1061

 private performResize() {
    const isImmediate = false;

 ...
      // Store the current position presentations for each viewport.
      viewports.forEach(({ id: viewportId }) => {
        const presentation = this._getPositionPresentation(viewportId);

        // During a resize, the slice index should remain unchanged. This is a temporary fix for
        // a larger issue regarding the definition of slice index with slab thickness.
        // We need to revisit this to make it more robust and understandable.
        delete presentation.viewReference.sliceIndex;
        this.beforeResizePositionPresentations.set(viewportId, presentation);
      });
...

Steps to Reproduce

Before window resize:

After:

After scrolling up - "fixes" window levels:

I noticed that the sliceIndex was less for the Axial view vs. Sagittal and Coronal:

The current behavior

See above in Steps to Reproduce

The expected behavior

The Axial view should behave like the other viewport for Sagittal and Coronal.

Hmm, can you share anonymized data? also can you try 3.10 latest?

[ahlaughland]

I'm currently upgrading to 3.10.0-beta.91 so I can test that when I'm done.

Github is not letting me upload my .zips <!-- Failed to upload "t1.ct.zip" -->

Here is the NM from anohter issue: #4519 (comment)

I'll try to upload the CT again later.

I got OHIF 3.10.0-beta.91 running locally and tested with my data and I'm not seeing the scrolling issue.

I'll close this now because it looks like the update will fix this.
