Unable to filter search results from the column header

The behaviour has been reported so far in Firefox, IE ad Chrome on the Windows and Chrome & Firefox on OSX.

Video attached of the click not extending the JQL query with ASC or DESC when expected.

No errors are generated within the log when the behaviour occurs.

I've also attached the developer Tools view which displays the following briefly when the event occurs:

onselectstart="return false;" unselectable="on"

Workaround
Manually adding the 'ORDER BY' argument does work. The behaviour does not always occur.
