BR tag inside the autoresize textarea makes textarea higher than wanted - Here is a fix

[bongobongo]

Hi.

Just installed this awesome plugin.

Found one issue though...
If I enter BR tags inside the textarea (entering raw text in Joomla textareas, where HTML tags are allowed)... then the textarea grow vertically for each BR tag added.

Is it possible that you could add a fix or a workaround for this issue?
I know it can be avoided by entering the tags using the &lt and &gt notation... but that makes the text pretty hard to maintain as well as the readability is getting messed up...

Here is my proposal for how to fix this:
When copying the content of the textarea into the DIV which is used to get the height... replace all the instances of
or
with or , just so the same amount of character space is used, but characters which do not affect the height of the div.

Just found out how to do this with some help from a RegExp expert on forums.devshed.com :

The goal is to replace the BR tags with GR tags... in HTML a GR tag has no meaning, so it will not make the shadow div (the one that is used to measure the height) grow. To make it work properly I just replace the letter "B" with a "G" inside the tag, and does not remove or change anything else. It is a case sensitive replace, since we want exactly the same space used in the div as in the textarea. Here it is:

if I enter the code below at the beginning of the "function textarea2div(text)", in your script, then br tags inside the textarea does not cause unwanted newlines (one for each br tag) to be added to textarea. If someone knows how to do this in one call to replace, please post it here:

  // replace all br with gr (case sensitive)
  // handle lowercase "b"
  var re = new RegExp("(<\\s*)b([rR]\\s*/?\\s*>)","g"); // NOTE: double backslash "\\s" becomes "\s"
  text = text.replace(re,'$1g$2');
  // handle uppercase "B"
  var re = new RegExp("(<\\s*)B([rR]\\s*/?\\s*>)","g"); // NOTE: double backslash "\\s" becomes "\s"
  text = text.replace(re,'$1G$2');
