Subject: [PATCH] Toolbar: ignore modifications on readonly textarea

CodeMirror forces WikiEditor to load. While CodeMirror handles readonly
textareas, the WikiEditor toolbar doesn't. CodeMirror and
syntaxhighlighting is pretty useful in readonly actually,
so I'm making WikiEditor a tad more resistent against readonly mode.

Bug: T188817
