@racostas is this ready for your review?

Yes, I did a first pass with him "in person" before the end of the GSoC period. The comments were properly addressed but it's missing a second test/review. I had been a bit taken with CCNA upgrade since them. If after second review there is something to fix I will take care myself.

Thanks @racostas

@SantiagoTG or @driusan or @ridz1208 could you please suggest/nominate an additional reviewer on this PR?
Just to confirm the Issue tracker comments/description will work as intended by the team.

Then it should be ready to merge to help our GSOC student wrap up his summer. thanks!

Everything works well now. The only thing (but I don't think it's related to this PR) is that the "New issue" page does not load because there is a missing jsx/Form import for FileElement. This can be solved by adding this line in IssueForm.js

I added it to test. Even though it's not caused by this PR I think it would be good to fix here

Yes, definitely something we can address in as part of this PR too. Thanks Camille.

ready to be re-reviewed.

@racostas I have tested the changes, and they work as expected without any issues. Looks good to me!
