Rule design view does not render in IE11 11.0.44 and Edge 40.x



Rule design view does not render anything on the browser, if one opens a rule in Pega Designer Studio on IE11 v11.0.44 (Released on July 11th) or an Edge browser (for example, section and flow rules).

Error Messages

Not Applicable

Steps to Reproduce

1. Login into Designer Studio on a IE11 v11.0.44 or an Edge browser.
2. Open a rule that has a Design view e.g. section.
3. Verify if it renders content on the browser.

Root Cause

The below styles/css are referenced in 'pzDesignViewInclude' section. When removed, rules load as expected.

<pega:include name="RulesSpaceStyles"/>

<pega:static type="style" app="webwb" path="css">
<pega:file name="pega_yui_container.css"/>
</pega:static> There are syntax errors in pega_yui_container.css and RulesSpace.css rules that are responsible for the reported issue.
