json.decoder.JSONDecodeError: Invalid \escape: line 1 column 386341 (char 386340)

This occurs when loading a JSON string with the following (the position 386341 is the s in \\"<\\script>\\"):

{"lno": 464, "bounds": [7, 11], "line": "return{send:function(r,i){t=de(\"<\script>\").prop({charset:e.scriptCharset,src:e.url}).on(\"load error\"", "context": "", "contextsym": ""}

MRE:

import json

json.loads('["<\\script>"]')
# or
json.loads(r'["<\script>"]')
