Column ordering is not working

Hi, i'm noticing that the column ordering for tables is not working. I've tried in two ways... by dragging the column in the data table, and by going to "Settings" and dragging in the column list. In both cases, after I drag the column it just resets to its last position.

This seems to happen if I have some hidden columns (if I click on the "eye" to hide them).
If I unhide all the columns, then the ordering works.

Can you post diagnostic info?
