timeSinceTopologyChange is still a varchar

I am trying to set an alert on event “STP Topology change”
I found this bug: STP alerting · Issue #3023 · librenms/librenms · GitHub

Is it resolved? It seems to be still present, in fact the field is a varchar instead of an integer:

timeSinceTopologyChange | varchar(32) | NO | | NULL

I have to run manually:

ALTER TABLE stp CHANGE timeSinceTopologyChange timeSinceTopologyChange INT UNSIGNED NOT NULL

???
