'Add' table name incorrectly overwrites cursor text

[bsmth]

Describe the bug

If I use the Add button from the schema explorer with text selected, additional single quotes are added to the end of the string.

To reproduce

1. got to https://demo.questdb.io/
2. type test and select this text in the SQL editor
3. click the Add button on the telemetry table in the schema explorer

test should be replaced with 'telemetry' but instead is replaced with 'telemetry''

Expected Behavior

Selected text is completely overwritten and closing single quotes are not duplicated.

Environment

- **QuestDB version**: 6.2
