Column breakpoint offsets appear to be codeunit-indexed, but column offsets are codepoint-indexed, so they render in the wrong place.
This is probably due to using Codemirror's column offsets, which appear to also be codeunit-indexed. Looks like we'd have to explore fixes to work around that.
Given code like
"😋😋😋😋";console.log("log3");
each smiley is treated as 2 columns wide, so the you get what you see in the attached image.
