After filtering and then selecting, it is impossible to select another element since the checkbox steals the focus.
You can verify this easily in your demo:
- Filter an employee name
- Select a row using the checkbox
- Try to open the dropdown for the datasource count ("1,000 Rows and 11 Columns")
- The dropdown immediately closes because the checkbox gets the focus
This does not happen until filtered. Resetting the filter doesn't help - once filtered, this happens while at least one checkbox is checked.
I checked the Browser's developer tools and noticed the checkbox gets the focus automatically during mouse click event.
I tried it in Firefox 72.0.2 and Chrome 79 and it happens in both.
I really would like a workaround until this is fixed!
