I think that the general solution to this type of problem is to increase the number of page sample in the statistics.
This settings worked for me:
innodb_stats_sample_pages = 32
innodb_stats_on_metadata = OFF
I have several problems across the database where the statistics and query plans were incorrect, and this setting has solved them all.
