MySQL has a special case for escaped LIKE wildcards appearing in string literals: the escaping is ignored, whereas normally for any other (non-special) character, the backslash would be stripped. This is implemented with a new flag on dialect which gets passed into the tokenizer, because I don't know if any other dialects have similar behavior and wanted to make it easy to add them if they do. I can't currently test Snowflake, BigQuery, or Clickhouse on this point, so I'm just going off my best guess based on docs and examples.
