I'm using Angular JS v1.1.5, and found an interesting IE-related issue.
In IE 9, 10, 11 and Edge, the following does not seem to work, even though it works fine in Chrome:
<div style="width: {{progress.percent()}}%;"></div>
Whereas this works in all browsers:
<div ng-style="{width: progress.percent() + '%'}"></div>
I'm curious why the first option doesn't work in IE/Edge. Are there any known bugs around this?
