[Bug 1578900] [NEW] file chooser broken since last update

[Conrad Firm]

Public bug reported:

since last update (maybe a week? two weeks?) whenever I use the
Open/Save option, the file chooser/browser works very, very badly...

none of the "Places" shortcuts, on the LHS, work - neither do the
"Devices" shortcuts

as for my own "Bookmarks" shortcuts, they appear to be suffering from
some kind of "sticky click" where as soon as you click on one, it tries
to move this to somewhere instead of activating it - only if you put it
back where it was (or move it up or down among the other Bookmarks) does
it actually function and allow you to choose a file path

I have attached a screenshot to help demonstrate this (note: choosing
the file to attach to this bug report had the same issue - even clicking
on the path along the top behaves erratically)
