Grants in prepare with 2 triggers on the same table

I can`t edit my own issues, and I marked the wrong version of percona () to fix it I create this new issue...

When using prepare and make update with prepare and have 2 triggers on this same table, then he asks of grant for not this user:

But when I use prepare:

user2 make update on table2, no table1... On table1 make INSERT triggers with definer user1:
