Status for Issue UE-210200

Last year, the bug ticket UE-210200 was created for us.

Enhanced input actions with Down triggers mapped to gamepad buttons can get into a bad state after viewport focus is lost

We recently noticed, that it was marked as duplicate.
As this is marked with Target Fix = 5.5: Is a fix for this issue already available with 5.5.3?
And what would be the ticket number of the duplicated issue (and Changelist Number if the fix is already in), so we can verify that our issue is resolved?

Thanks.
