I'm working with a legacy enterprise site and have a question about the current state of Magento and prototype.
I've read that when prototype 1.7 was released it resulted in issues with IE9 in Magento. At the time, to resolve this issue our developer forced all versions of IE to use IE8 document mode using:
<meta http-equiv="X-UA-Compatible" content="IE=8,chrome=1">
Additionally, prototype was downgraded to 1.6.1. This issue and solution are further documented in this issue. Further solutions for this issue are on this page (Google cache used as source site is down for maintenance).
Since this initial change, we have upgraded Magento to 1.13.x. Along the way prototype was upgraded and the site is currently using version 1.7.
What I'd like to do
I would like to restore the meta tag to the following to improve experience on IE9+:
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
Clearly, forcing IE8 document mode is not ideal because it disallows IE9+ from displaying features it supports and results in an overall poorer experience. using
IE=8 solved the issue at the time, but does this original issue still exist?
Am I able to use
IE=edge with prototype 1.7?
