accidental-markup

hint by default

A style mark in text that is never closed, such as the * of "5 * 3", so it is written as the character itself. The fix puts a backslash before it, which says so.

Changing it

Set the rule's severity in mms.json, to error, warning, info, hint or off:

{
  "lint": { "accidental-markup": "off" }
}

To silence it on one line, write // mms-ignore accidental-markup on the line or the line above. See Lint rules in the guides for more.
