I eventually learned to place the cursor, squiggle a little random swipe (and a blank) that I can then select and replace. It's certainly an unintuitive nuisance, but my personal biggest issue is something else:
No advanced keyboard seems to have a setting to not force an automatic blank after each and every swiped word, no advanced keyboard beyond the original Swype that was abandoned a long time ago. Some have elaborate workarounds for fixing blanks before punctuation, but none seem to allow to leave space bar operation to me. I use a lot of composite words (hello from Germany) and the forced blanks are just infuriating. So I use anancient keyboard that was abandoned at some point between flappybird (composite word!) and 2048 or earlier and can only hope that Android keeps doing acceptable backward compatibility...
have you tried florisboard? i would probably use that as my main keyboard but the way it doesn't add a space after words when you swipe something kind of bugs me, especially after getting so used to it with other keyboards
