Switching to System>HTTP auto expands all then collapses

I noticed when I went to System>HTTP, that behind the normal loading screen, every field was expanded. I could tell this because I saw traces of red where there is none once the field loads in addition to the page contents being longer then loading shorter.

While reproducing I also noticed that intermittantly, I would get a message prompting me to discard/save changes even though I was going to/loading this page.
This may be a distinct issue, however, mentioning here because the video I captured, this happened twice. The third time (on video) it did not occur and shows the behavior without this.
I left minor in case this is two issues in one, that one is rather perplexing, otherwise this would be trivial.
Let me know if not clear.

I did not check older versions of NX3 or NX2 at this time.
