Dashboard page layout expands on every change

### Current Behavior

Hi,

In Dashboard 2, whenever a flow is updated, the Layout \ Pages overview refreshes and expands all Pages & Groups. There has already been at least 1 request to change this behaviour, and there seem to be some technical issues in solving this.

Again, I would like to say that this is extremely annoying behaviour. We have Dashboards with 10+ pages, and several groups within each page. So scrolling to find a page or group is very time-consuming and .. well.. annoying. And not exactly contributing to ease of use.
If a technical solution for remembering the last state of that overview is difficult for some reason, please, please, please make a button to collapse all pages and groups. That should make it much easier to quickly find the page\group you're looking for.

Thanks! DenW
