data-diff +/- symbol renders outside of code block in first line

[fry69]

I am currently on my way through the tutorial and noticed that if the first line of a code block is subject to change, the +/- renders outside the code block, see attached images. I tested this with current Safari (16.6) and Firefox (116.0.3). The images are from Safari from the following two URLs

Searching for a prior I did not find any other bug mentioning this, also the data-diff arguments seem to be correct, so it must be bug in the highlighting code, but I have to clue where to look for this.

Tiny plug: I stumbled over #1534 and would love to see a before/after/diff view rather than this +/- view only.

Fix for this bug was merged into ember-showdown-prism. This issue can be closed when the fix arrives here.
