What did you do to cause this?
Attempting to click on the 'heading' within a type for use in filtering.
What page were you on?
What PHP and MariaDB versions do you run?
MySQL: 5.1.73-1-log PHP: 5.3.3-7+squeeze18
Describe the defect:
Ticket #394 added the ability to "select all" of a category by clicking on the heading for use in filtering.
This no longer appears to work in 3.4.1.
Clicking each of the sub-items, or ctrl-/shift-clicking for multiple selections still works as expected.
