CPX MakeCode, snail mode, forever loop doesn't highlight

[ricknun]

Describe the bug
Microsoft MakeCode for Circuit Playground Express: In snail mode each statement is highlighted as it is executed. A "repeat" loop highlights as expected (see the image) before executing its contents. But the "forever" loop does not highlight. In the program shown execution appears to go from "clear" to "repeat 4 times" without ever highlighting the "forever" block.

Additional context
I was using this program to teach my 8 year old grandson about nested loops, explaining that the highlighted loop asks "Should I do it again?" But the forever loop didn't pause/highlight to ask that question, so I had to explain what a software bug was, etc.
