Summary:
Each file downloaded would open finder and show the path to the file. Users were reporting that this felt excessive when downloading multiple files all to the same location #1044. I added a check to see if the path was the same as the previous file path, and only showed the item in the folder if these differed.
Also added tests for this in file download store.
test(downloads): Add tests for showing item in folder only if lastDownloadDirectory differs
Test Plan: Added tests to file-download-store-spec
