1. Add release using harmony from spotify.
2. On release actions page, open in new tab - a) add isrcs using magicisrc link and b) add spotify track link to recording.
3. Now that both tabs are open, submit isrc first, then change tab and submit edit for adding spotify track url.
4. observe 3 edits took place: a) isrc submission, b) adding of spotify track url and c) removal of isrc from the recording.

Here the edit c) as above is the bug since isrc was not explicitly removed by the user.

Hypothesis is that when tabs are opend from harmony, the isrc is not present in the recording and hence the form of recording edit gets opened with a blank isrc. However since isrc submission took place before the addition of url relationship to the recording, when submitting the recording edit with blank form, it is counted as removal of isrc.
