main: fix global click handler

settings view and write new message didnt show. reason was typescript
expected an instance of an HTMLElement but this didnt allow for
SVG elements inside the write button. Another reason was that the
condition expected a parent with data-id which isn't the case for
settings button nor write-new-message.
