jquery - How to change jQuery terminal --char-width

Question

I am using jQuery Terminal 2.4.1. In Chrome the Terminal allows the user to type characters only half of terminal width and it wraps. Firefox it works fine.

The only difference I am seeing is --char-width is 7 in FF and 12.7344 in Chrome. Is it calculating the line wrap width wrongly and getting truncated half?

If I set width like below, it wraps properly and occupying full window width

Ext.getElementById('terminalContainer').style.width = "180%";
terminal.resize();

However then the vertical scroll bar is hidden.

How can I set --char-width in Chrome?
