Fix wrong bracket match rectangle on auto format

This commit fixes instances when setText is called on editorTab and the rectangle that highlights the bracket match becomes incorrect.
This is because text is inserted to the document without notifying the textarea.
Calling setLineWrap internally fires an event that recalculates the bracket match rectangle and thus solves the problem.
