I inserted an image into a custom highlight on B2, and I could never get it to work, even though I tried a variety of sizes and image formats, all it show was a square.

So I bounced over to L4.1 B2 to see if the input mechanism for the highlight style was broken on Mac and found this:

The input mechanism was fine, L4 Mac B2 simply won't show the image, where as L4.1 B2 will. So, faithful Mac Dev team, what type of information would you like? If logs, do you want logs from the creation of the style of some other time period?
