Problem description: I added a formula in a document: A = {1} over 1+x newline B = sqrt{1 over {1+x^2}} I close the formula editor. Then I double click on the formula and modify the formula: A = {1} over {1+x} newline <- I added {} B = sqrt{1 over {1+x^2}} Now, I try to undo the addition of {} via ctrl + Z. The undo is wrong.
