There are several UI issues.
==={icon spinner color=blue} The icons are too small (both IE10 and IE11)===
{F9026427 size=full}
{F13635377 size=full}
==={icon spinner color=blue} Extra x is displayed (both IE10 and IE11) {icon question-circle color=blue}===
{F13636577 size=full}
This **x** is working and might be desired, unlike **x** on T187049.
==={icon spinner color=blue} Refresh button too big - IE11===
{F13635490 size=full}
This one is probably present on IE10 as well, but Suggestions don't work on IE10.
==={icon spinner color=blue} List item actions overflowing - IE10===
{F13635601 size=full}
Works good in IE11.
==={icon arrow-circle-up color=green} Personal menu icon and indicator displaced when clicked - IE10===
{F13635710 size=full}
Works good on IE11.
This problem is coming from #ooui. Ticket to track {T187243}.
