Upgrading to bootstrap 3.3.5 meant that checkboxes inside a div with
column-count:3 set would be unclickable in Chrome: in fact, the entire
div appears to sit on top of its contents, making interaction impossible.
This affected both the 'show folder with these devices' and 'these devices
can access this folder' sections of the UI.
I'm not sure what the the underlying cause is, but moving to Bootstrap's
grid system appears work around the issue. Devices/folders have to be
explicitly split out into rows, otherwise the final element appears offset.
To do this grouping by row, a new filter (groupFilter) has been added, which
turns an input of e.g. [1, 2, 3, 4, 5] with a groupSize of 3 into
[[1, 2, 3], [4, 5]]. However altering the collection in this way throws
Angular into an infinite watch loop, terminating in infdig. m59peacemaker's
pmkr.filterStabilize (MIT) was added to work around this issue.
This also has the nice side-effect of wrapping the list of devices/folders
when the screen width decreases.
