Index column has a null value

[abey79]

Notice the first two rows with duplicate frame_nr number, even though frame_nr is the index column.

edit: the first row as a null frame_nr value actually (it just happens to be displayed as 0 here for some reason). See my comment below.

Can't repro:

cargo r --all-features -p re_dataframe --example query -- /tmp/face_tracking.rrd frame_nr 0 4 /video/landmarker/faces/0/landmarks
