event create: page jumps up twice. user doesn't see loading wheele

[1u]

what happens:
after clicking "Save" the page immediately jumpst to the top (scroll position). and it still shows the editable form. only after some seconds it shows the normal (not editing) view. I got irritated, if it was saved now already and why it shows a form again.

(when I scroll down it shows the loading wheel in the save-button, and eventually jumps up again when showing normal view)

what should happen

• either show a loading wheel at the top of the form
• or I guess much better: don't jump up when saving is triggered.

Can you reproduce it or was it an isolated event? What Browser are you using?

I was unable to reproduce this in Firefox 62.0a1. How I tried to reproduce it:

1. Go to course on staging.openki.net, log-in as admin
2. Choose course at random
3. Click add-event
4. Scroll down to save-button
5. Unplug network-cable
6. Click "save"

The button disables "saving..." and the page doesn't jump. Soon after plugging the cable back in, it shows the created event. So in my case it works fine.
