I have set up a custom image highlight function that I have created and registered to the sheet with setCustomHighlightImgFunc. I then call addHighlightImage(id) and the highlight is correctly attached to the image. However, when I call removeHighlightImage(id) with the same id, the highlight is not removed. Is there another method I need to call to render the removal?
Also, when I call setHighlightAll(false) on the sheet, it applies the image highlight to all of my images, even if no highlight was added to the images. What should be the result of setHighlightAll for images?
