Description
When removing an entry from the expiration queue,
x/feegrantuses the key with the granter/grantee inverted. The correct key isfeegrant.FeeAllowanceKey(granter, grantee), notfeegrant.FeeAllowanceKey(grantee, granter). This prevents proper deletion of the allowance entry.Patch-style hint
Impact
Expiration not actually removed for the prior grant.
Recreated grant can be deleted later by the leftover (stale) expiration event.
