Dialog for number filter closes when using arrows

[cf_Simon]

Hi,
when using the arrows to in-/decrease the value of a number within the filter dialog, that dialog get closed when the arrow is clicked.
Makes it hard to go up/down more than one step. It would be good if that arrow can be clicked multiple times without having to reopen the dialog
