There are several UI issues.
- The icons are too small (both IE10 and IE11)
- Extra x is displayed (both IE10 and IE11)
This x is working and might be desired, unlike x on T187049.
- Refresh button too big - IE11
This one is probably present on IE10 as well, but Suggestions don't work on IE10.
- List item actions overflowing - IE10
Works good in IE11.
