Search by JSON keys works incorrectly about manticoresearch

Escaping with backticks doesn't help either:

➜  ~ curl localhost:9308/search -d '{"index":"t","query":{"in":{"any(a.`-1`)":[1]}}}'

{"took":0,"timed_out":false,"hits":{"total":0,"total_relation":"eq","hits":[]}}%

➜  ~ tail -1 /opt/homebrew/var/log/manticore/query.log
/* Wed May 01 10:51:45.434 2024 conn 1146 (127.0.0.1:54192) real 0.000 wall 0.000 found 0 */  /*{"index":"t","query":{"in":{"any(a.`-1`)":[1]}}} */
