I was able to find this old question with the only comment saying “this was fixed” but honestly, it isn’t.
For example, I have this formula:
You can see that the forumla popout covers the relevant referenced cells pretty badly (BT25 being under the 0),3,0 part and BP25 being under the 25+BX part, while BX25 is half visible). I’ve got dozens of formulas like this that reference adjacent cells, and given that the formula bar exists, I don’t need this in-place popout.
I’ve running version 184.108.40.206, which I downloaded fresh just the other day.
