The Dart Theme uses:
<SPAN class="selector token">.jimu-widget-frame.jimu-container *</SPAN> <SPAN class="punctuation token">{</SPAN>
<SPAN class="property token">color</SPAN><SPAN class="punctuation token">:</SPAN> #ffffff <SPAN class="important token">!important</SPAN><SPAN class="punctuation token">;</SPAN>
<SPAN class="property token">outline</SPAN><SPAN class="punctuation token">:</SPAN> none<SPAN class="punctuation token">;</SPAN>

Dart Theme is the only one causing problems like this. What can we (or ESRI) do about this?
Thanks in advance for your answer!
