When I am in the note field editor and want to change the float of an image, the user interface has the correct title text for its functionality, but the icons seem to be the wrong way round. The first group contains the float buttons: the leftmost button says “float left” and makes the image float left but shows an image floating on the right, and vice versa for the rightmost button.
I have restarted Anki with plugins disabled (Shift key) and this issue persists.

I hope this is helpful - please let me know if you would like any more information.
