Group page does not load properly in IE11
Summary
The Groups page doesn't load on IE11, and shows a Javascript error. I noticed this on a self-hosted gitlab-ce instance when I applied the security update to 11.3.1 (was previously on 11.2.3, which was not affected by this error), but it also happens on gitlab.com.
Steps to reproduce
Go to any group page, for example https://gitlab.com/gitlab-org/ using IE11 (I am using version 11.0.9600.18537)
What is the current bug behavior?
In the main window, nothing below the three 'tabs' (Subgroups and projects, Shared projects, Archived projects) shows up. In particular, you can't see a list of projects in the group. See screenshot (also includes the F12 developer tools debugger).
What is the expected correct behavior?
A list of projects should be displayed below the three tabs
Relevant logs and/or screenshots
The F12 Developer Tools window shows the following Javascript error (in the screenshot above)
