PageBuilder lacks Undo option

[lbajsarowicz]

Description (*)

The one is related to the #494 issue. When you try to click the element, the toolbar appears with delay and actually catches the click on the element as a click on thrash icon, so it's removing the element without any kind of confirmation.

Expected behavior (*)

There should be an option to revert the last step.

Benefits

Even if PageBuilder generates issues, you can always rollback last action.

This is a great UX improvement and we've considered it during our internal grooming. The level of effort required to implement it is quite significant compared to the value it adds. There is no capacity internally to develop this. We'll work with community on the implementation of this and assist with delivering.
