Find and Replace deletes text lines of words that expected to be replaced
## Expected behavior, english is recommend
While I do Find and Replace all the lines that have been found at flygrep are replaced to replace value.
## Actual behavior, english is recommend
While I do Find and Replace (SPC-s-/, {enter replace pattern}, Alt-r to enter replace mode, ESC to end editing, ESC to confirm) the editor removes everything that matches the search. Tested only on python layer
