The "Delete auto-follow pattern" table action does not work in IE 11.

Steps to reproduce

• Create an auto-follow pattern
• In the table view, click on the "Delete auto-follow pattern" button

Expected behaviour: a modal to confirm deletion should appear

Current behaviour: the modal does not open (no error message in the console).

If we select the pattern in the table and go through the "Manage pattern" to delete it, the modal does appear and we can delete it.

EDIT: After some more testing on IE 11 and CCR, it seems that the same issue occurs in the Follower indices table. The first and last item ("pause..." and "unfollow...") of the actions in the table does not work.

cc @elastic/eui-design Is this a known issue on IE?
