No "squigglies" under TypeScript files with errors Follow

If there are errors in a Java file, those are indicated with red bars in the scrollbar area, as well as red "squiggly underline" in the Project file list and tab titles. I would like to see the same for TypeScript errors. Currently those are only indicated in the scrollbar area once inside the file, but not un the Project file list and tab titles. Or am I missing some setting required to "enable" this feature for TS files?
