Title: remove raw cell placeholder on focus, closes #5238

Unlike markdown cells, when Raw text cells are "rendered", the codemirror instance is still visible. This PR makes it so that when the CodeMirror instance is focused (which you can do with a click selection), that will trigger an unrender event.
