A text area is created and the overflow attribute for it is set to hidden. Then
text is set in that text area which flows past the end of the text area and goes
into the overflow area. Holding down the delete key in the text area for ~10
characters causes the browser to hang indefinately.
Below is a small sample file which I use to reproduce this. Click on the text
area and hold down delete and the browser will hang.
Also, this problem occurs if rather than holding down the delete key there is an
attempt to change the value in the text area through the DOM.
ie : adding a button to the form which has an onClick() that calls a function to
do the following :
document.msgText.value = 'bla';
will also hang the browser.
