Fix wrong bracket match rectangle on auto format

[magedrifaat]

This commit fixes #9544
When setText is called on editorTab 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.
A more straightforward way would have been calling the function
"doBracketMatching" on textarea but the function is protected.
Actually setLineWrap is the only public function that I am able to find
that internally (eventually) calls doBracketMatching.
I am not familiar with your testing framework and couldn't find any
information about it to run the tests so I only tested the changes manually.
