I don't know when they made the change, but now in Google Data Studio, if you are in edit mode, and you make changes it shows live preview. Like, if you click in the wrong place of a filter, it will actually show the filter drop down so you can edit.
For example, in the screenshot below, you can see I am in edit mode but when I hover over a chart it shows me live data like if I was in view mode.
How can I turn this off?
