drop-downs not compatible with mac scrolling

If I use a filter and look at results, I can click the button for "Columns". The drop-down has a lot of items. If I scroll using the trackpad, once I stop scrolling, the list snaps back suddenly to the top. If I use the wireless mouse I have, this doesn't occur. Unless someone knows the work-around and has an external mouse, the drop-downs may become unusable!

We are using a hosted version of JIRA, but it is fairly new.
