I have a web application where I\'m specifying an input field to be a number using the HTML5 property type=\"number\".
Why would you want to disable localized formatting? If you want a different format, just change the localization settings of your PC. Why would a user not be interested to show a number in his or her local format? This is definitely not a bug in Chrome but a feature!
It seems to me you are not really using a "number" as input but rather a "text" code with a pattern. See the other posts for suggestions to that.
