Steps to reproduce:

1. Navigate to Zabbix Web Interface - > Monitoring -> Maps
2. Create or edit a Zabbix Map.
3.  Add or edit a map element 
4. Set:
   1. type - trigger
   2. Choose a disabled trigger
   3. Apply
5. Update

Result:

As we can see on the next picture, the host presents state OK, if we choose on previous step 4.1 type - host a disabled host, this host will comes up disabled on map (as we expected for triggers too). This behavior happened on Zabbix 5.0.4, 5.0.6 and 5.2.2. We made exactly the same steps on Zabbix 4.0.13 and 4.4.9 and the map element became disabled as we expected. (We tried with the most basic and many others map properties, but we couldn't make the map element become disabled)

Expected:
As explained on previous topic, we expected the map element with a disabled trigger could be disabled too on the monitoring map screen, as we can see on next picture (Zabbix 4.4.9 and with the same map properties and map element configurations):
