HandleExtraFileTypes does not preserve subtitle "Label" property

While implementing a custom reader that extends ImagePlus, I was trying to set the "Label" property (via imp.setProperty("Label")) so that the subtitle shows up nicely in ImageJ.

When I call my custom file format reader plugin directly from File>Import>My Custom File..., the Label property is shown in the ImageWindow's subtitle.

However, when I integrate my reader into HandleExtraFileTypes.java, the Label property is not shown in the ImageWindow's subtitle for images opened by File>Open... or by drag and drop.

I was able to fix this by inserting the following code to preserves "Label" property in the HandleExtraFileTypes.run() method, as follows:

// also copy the subtitle ("Label") field over if it exists
if (imp.getProperty("Label") != null)
    setProperty("Label", imp.getProperty("Label"));

I am not sure how to locate the canonical HandleExtraFileTypes.java. There seems to be one hosted on the ImageJ1 plugin server (source). I do not see one on the ImageJ1 git mirror. Perhaps the version in the ij1-installer project is canonical?

Anyway, I am not sure where or how to submit a patch, so I am just posting to this mailing list. Let me know if there is a better place.

For use at my company, customizing HandleExtraFileTypes is ok. But I figure it would be get to get this fix to other users if possible.

Note I only tested this with ImageJ1, version 1.49p.
