[Timebox] Record group create new record issue

[magrinj]

Issue:
When creating a new record from the "+" button in record group mode on the table, a pending row appears. The dropdown closes as expected when the user selects a record group in which they want to create the new record.

Problem:
If the user does not fill in any data in the pending row and clicks outside the row, the pending row remains visible instead of disappearing.

Expected Behavior:
The pending row should automatically disappear when the user clicks outside the table without entering any data.
