[Koha] Tabs display in catalogue editing mode

[Elaine Bradtke]

We just updated to 18.05.05. Now the tabs are displaying strangely -
covering the buttons (and less often, the buttons hide the tab numbers).
But it's only a problem with some of the tabs: 1-4 and 8-9. The buttons and
tabs still seem to function, but they don't display correctly.
It also only seems to happen in Chrome (it works fine in Firefox). I've
cleared the browser history in Chrome and restarted it, but it persists.
Any thoughts?
