Bring user's attention to element affected by undo/redo

[jarekdanielak]

Problem you would like to solve

Currently there is no visual indication of undo/redo changing an element. This means that when mass-undoing/redoing, you can miss a change made in some part of the diagram you weren't paying attention to.

In the below example, I:

• add an execution listener,
• go to some other task to edit properties,
• decide to undo them,
• hit undo one too many and remove an execution listener.

Proposed solution

After a discussion with @lmbateman, here are some ideas to make sure changes made by undo/redo don't go unnoticed:

• auto-select element(s) modified by undo/redo,
• (optional) open properties panel if change is visible there
• (optional) open affected properties panel group (e.g. expand Execution listeners section if undo removed one)

Alternatives considered

Leave it as it is if it's not a concern for users.

Additional context

Would fix #4772

I think this is a valid request, though I'd rather not prioritize it as I've never seen any users complaining about it.

@jarekdanielak As we have elements.changed as a general feature available you could fairly easily try this, today. I'd add the spring cleaning tag, and/or consider to slack on this, one day and see how it feels.

Thanks for the inputs. I'm adding it to backlog as a spring cleaning item, hope to slack on this soon.

Given that undo and redo are even more context sensitive than before I'd expect some sort of visual feedback for it happening. :)
