Drag n Drop selected Text from Safari, chrome not working on indesign CC

In CS6 If we drag drop any selected text from any app on layout it work but in indesign cc it is working only with some app like TextEdit, notes etc. I knew that very few people have such use case but same is also not working from one of my cocoa app.

while  debugging if i drop content from TextEdit and Notes app on some sample app I found that TextEdit & Notes App registered for this Extra Pasteboard type "com.adobe.indesign-import-ustl" and "com.adobe.indesign-import-styl" where as chrome and safari are not. similarly my app is registered only for "NSPasteboardTypeString" type. Is this is the limitation or bug of indesign?
