The "Undo last scan" button is missing from the "Delta-over-time search" tab of the "Memory Observer" window of the PCSX-Redux PlayStation One Emulator

I am just migrating the #1102 feature request from the Discussions tab to the Issues tab according to wheremyfoodat's request:

> Could you try using the issues tab for feature requests rather than the discussion tab?

Now, unlike discussion, you can close this issue when this feature is implemented in PCSX-Redux.
