* SUMMARY
Inline errors on neighboring lines may collide if expandable.

console.error("really really long error message that will need to be expanded");
console.warn("warning will collide");
</script>

* STEPS TO REPRODUCE
1. Inspect test case.
2. Jump to error

I knew about this issue, but I don't consider it that important to fix yet. I don't think it is a common case to have errors on adjacent lines. I also don't think it will be common to need to expand errors (truncation, or multiple errors on a line).

I think until this is actually seen in real content, or if it becomes an issue with more frequent inline warnings (lint messages) it is low priority.

I don't know what the ideal behavior would be here anyways.

  - We could just switch to a pop-over, but I don't think that is as nice.
  - We could check for overlaps and also expand the other inline error/warning, etc.
