Not able to delete negative sign using backspace button

[TathagatIVP]

Describe the issue and the actual behavior

When the negative sign is removed from the prefix using backspace, the negative sign is automatically inserted when the focus is moved out. It functions when we hit the -key on the keyboard, but not when we hit the backspace key to remove the negative sign.

Describe the expected behavior

negative sign should get removed if we press backspace button
