SUMMARY
Fixes #25597
When a tab is switched, the onSchemaChange action trigger is redundantly triggered with the same schema value. This causes the current table selection reset as recognize the schema switches. (This typically happens in SQLLAB_BACKEND_PERSISTENCE mode due to the sequence of api updates)
