Just found that WordPress 4.0 Beta 1 renders scrollbars a bit weird in IE
For example, check these results there https://shots.testize.com/Results/Shared/453ec369-658a-49ee-a222-09230b33bc74
I've highlighted places in IE11 & IE10 results where scrollbar overlaps the search area in the header.
Is it something that has been reported?
Do we have any quick fixes for this?
