I’m currently trying to implement a button in a popup that, when pressed, selects every row in the table beneath it.

The button uses the onClick event below:

```python
self.parent.parent.getChild("Table").props.selection.data = self.parent.parent.getChild("Table").props.data

```

This button works properly in every case _except_ for the first time that the button is clicked after the popup is loaded. When the button is first clicked, it _very briefly_ sets `self.parent.parent.getChild("Table").props.selection.data = self.parent.parent.getChild("Table").props.data`, before immediately setting `self.parent.parent.getChild("Table").props.selection.data = []`. All subsequent clicks of the button result in every row being selected as expected.

Is there a way to circumvent this behavior?
