I have issue with SharePoint 2010 and Markup styles on newer browsers.
On IE11 and Chrome (haven’t tested on Mozilla or Opera, but older IE works) there is issue that when you expand drop-down, all the options are empty (items are there, but no names) and if you click on them they don’t work.
I tried to look for the problem with developer tools, but all I could find was that some default SharePoint js crashes because it can’t find few elements.
Has anyone encountered this problem and know how to adapt markup styles so this bug wouldn’t occur?
