Summary

[thinkh]

Thanks for this change. While testing the filter I found the following bugs.

Filter icon still highlighted after clicking reset

1. Open date filter dialog
2. Select a date range
3. Click on reset

Observed behavior

The filter icon is still orange.

Expected result

The filter icon should not be highlighted after click on reset.

Edit min/max date filter

1. Open date filter dialog
2. Double click on min/max handler
3. Change date in input field
4. Press Enter

Observed behavior

The Enter key does not work and clicking outside is equal to cancel the change. Hence, it is currently impossible to change the date using the edit date dialog.

Expected behavior

Best case: Enter key is working to confirm the change (which would be conform with the number filter dialog)
Alternative: Add apply/cancel/reset button to this dialog

Looks good and works as expected! 👍
