Input line expression editor failure

[compsystems]

Hello

In the power operation, if the base is in brackets () and if you write a fraction and then place it in the history and then copy it to the input line, it no longer allows you to add operations to the fraction.

(-1/2)^2 [enter] [copy]

(|-1/2)^2 // The cursor | does not allow positioning before or after the fraction.
(-1/2|)^2

You have Entry set to "Textbook" in home settings, right?

Use the up and down buttons to move the cursor between the top and bottom parts of a fraction.
