CSS not applied until page interaction

We have run into an issue where css is not being applied in IE11 and edge until the page is interacted with. We use the cssselectorhelper widget to apply styling to an input for custom error messages. When the object is returned to the browser we can see the cssselector attribute change as expected. However, the css that is associated does not render until we move the mouse. This functionality works as expected in Chrome.   Has anyone come across similar issues before?
