Make find and replace in cell window floating in cell NOT stuck at the top!

Is your feature request related to a problem? Please describe.
The find and replace in cell 'ctrl + shft + H' is stuck at the top. When your code is longer than viewing area you have to scroll BACK to the top to find and replace the next item!

Describe the solution you'd like
The find/replace in cell window floats at the top so that the code can scroll underneath it. This means that it is no longer pinned at the top and you don't need to scroll back to the top when searching items and then replacing them.

Describe alternatives you've considered
You can hit enter key to move around the next items but need to either be on search (arrows) or replace to use enter to either search an item or replace an item. But you have to then scroll back up after verifying what item to search for or if skipping to next item.

Additional context
once you use shortcut the f/r window appears in cell

after scrolling down to lower code in cell it is hidden!
