4. Close/Reopen editor. Text looks ok.
It seems that text is inserted correctly, but it broke the projection document.
If <head> node is present, or if the file has no nodes, then the insertion is done smoothly.
Tests pass, but they only check the content and cannot find a problem in the presentation model.
It seemed to me that this feature worked ok previously, and file MobilePaletteInsertHelper had no major modifications. (Resolved issue JBIDE-15111 indirectly supports that it must have been ok.) Maybe this is only a local problem in my environment.
