Commas appearing in units about isaac-editor HOT 2 CLOSED

It's because you have gone from html encoding to markdown encoding. Markdown is the default the encoding for new content. Content which was imported appeared in html. I think the issue is just because markdown and html deal with latex math rendering slightly differently.

This is because the place you are copying from has an encoding of "html", whereas the place you are copying to has an encoding of "markdown". In markdown, the backslashes mean something, so to get an actual backslash you need to escape it - with another backslash! To get valid markdown, write {m\\, s}.
